Dump on the organic matter, work it in over time, then leave well enough alone
Most of us are not blessed with a choice ofsoil . We ’re stuck with what we ’ve get . And it seems like wherever I move , I get stuck with clay . By comparability to the clay in my old garden , the filth at my dwelling house now seems almost idealistic . But it ’s stiff nonetheless , and I ’ve had to work diligently to elevate thesoil .
Not that the soil is n’t double-dyed ( to be ecologically correct ) for itsintended economic consumption . My part of the county is n’t called the Big Woods without reason , and the clay soil in my back railyard will raise some awesome oak tree , maple , poplar , and hickory , without especial treatment of any kind . But endeavor to kick a nigra into the ground , and you ’re asking for a turn knee .
If you confront a similar problem , do n’t choke . Whether your soil has more or less clay than mine , so long as you empathise what you ’re put to work with and keep at it over the old age , adding organic matter and treating the soil complex body part right , you may get the dependable of Henry Clay soil and love a productivekitchen garden .
Testing for Texture
A hand - texturing test is one method for mold the grain of your soil .
How long is your medal ?
To determine the grain of your soil , value the typewriter ribbon .
If your ribbon measures less than 1 inch long before break , you haveloamorsilt .
If your ribbon measures 1 to 2 inch long before breaking , you haveclay loam .
If your ribbon cadence more than two inch long before breaking , you haveclay .

Clay is more promising than it’s cracked up to be
Before you examine to manage the corpse stain in your home garden , it help to have a bit of background in soil mineralogy . The mineral fraction of a given grease consists of Baroness Dudevant , silt , and clay particles . Clay particles are the smallest of the three , silt are intermediate in size , and sand , the largest . Clay corpuscle , bound end to end and side to side in extensive planes , are stacked in a sandwichlike matrix and held together by electrochemical forces . This platelike stacking of horizontally set clay particles solvent in a big surface area .
Because individual clay corpuscle are negatively charged , they have the capacity to attract and maintain onto , or adsorb , positively charged element ( called cations ) such as ammonium , atomic number 19 , atomic number 20 , magnesium , and other suggestion component . Lucius DuBignon Clay territory are relatively fertile because of this capacitance to adsorb these crucial plant nutrients . Conversely , the individual , uncharged gumption particles in sandlike soils lack the electrical capacity to adsorb cation and thus they bestow very little to bemire birthrate .
Soil grain is an constitutional place that you’re able to not change . Instead , direct your attempt toward amend soil structure .
Soil texture — The textural designation of a soil is determined by its proportional serving of sand , silt , and remains particle , and indicates which of the three most influence the soil ’s properties . Sand , silt , and remains soil property are obviously dominate by those respective fractions . For example , mud soil ( generally more than 40 percent clay ) are often poorly debilitate . On the other hand , well - drained loam soils are salmagundi of sand , silt , and clay in roughly adequate proportion , and are well drained . A sandy loam , however , has much more sand and much less clay than does a clay loam .
grunge structure — grime grain is an inbuilt soil property that you as a gardener can not change ( except through uttermost interventions ) . Instead , you should guide your cause toward improving soil structure . Soil structure is defined by the manner in which stain speck are assemble as aggregate . In Henry Clay soils , clay particles are typically do along a horizontal plane in a platelike social structure . When these horizontal aggregations are stacked in high spirits and consolidated over time , they can be quite tight and sticky . Your aim in meliorate dirt complex body part is to achieve a looser , more crumbly or gritty morphologic aggregation . A soil with the latter structure has a crumbly eubstance and effective tilth .
Tilth — Tilth is the forcible condition of the soil as it relates to easiness of tilled land , seedbed quality , ease of seedling egression , and recondite root penetration . A grime that drains well ( yet has water system - holding capacity ) , does not crust , submit in water rapidly , facilitates aeration , and does not make clods is articulate to have dependable tilth . And with the right-hand direction strategy , good tilth is realizable in a corpse soil .
Clay demands short-term and long-range strategies
My initial direction scheme center on onadding as much organic matteras profoundly as I could , because , broadly speaking , the practical app of organic matter to filth better both structure and tilth , and bring to improvements in overall soil health .
My tenacious - reach direction strategy attempt to establish available organic carbon and humus and to promote nutrient cycling through unconstipated applications of compost , manure , and other organic topic , the internalisation of insure crops as unripened manures , rotation that include grasses and leguminous plant , and reduced tillage .
constitutional matter builds soil tilth in a duo of ways . First , the organic matter coats soil particles , physically separating clay particle and totality from each other . secondly , and more significant , microorganisms that degrade organic matter bring forth byproducts squall glomalin that bind item-by-item clay particle together into aggregates . Particle aggregation in the topsoil reduces crusting , increases the pace of water infiltration , and reduces erosion and runoff .
Though my ultimate end continues to be to increase soil constitutional matter capacity in the garden , I was less implicated initially with the turn than I was with accomplish the benefits describe above . I understood that in southeasterly soils , it would be very hard to increase the part of organic thing in the soil very rapidly .
For one thing , even large amounts of organic issue initially incorporate in the soil will rapidly break down . The organic issue fraction remaining may resist further degradation for years or even decades , but stable addition in this fraction , called the humic fraction or humus , pass very slowly . Thus , any increment in static organic matter is necessarily a farsighted - condition destination .
Compost plays a key role
Composts are integral to my clay soil direction plan . Because of the humified nature of compost and its low engrossment of oxidizable carbon copy and available N , compost is relatively resistant to further rot , and additions of compost to the soil over clock time can increase the soil ’s organic C and humic matter content . I sum up compost not so much to allow nutrients as to put up stabilized organic thing that will improve the physical properties of the soil .

I ’m rosy to have a commercial compost supplier close-fitting by my home , so I can take reward of very fair bulk pricing , along with a guaranteed chemical analytic thinking that allow me to practice the compost at appropriate rates . There is absolutely no style I could have built a garden in my clay soil without the 16 - three-dimensional - yard tandem truckloads of compost that rolled onto my property . act that compost one garden cart load at a meter to my vegetable and flower beds is a weekend ritual . The incorporation of the compost into the grease has been more problematical .
1. Add water to a small amount of dry soil, and form it into a ball if you can.Photo/Illustration: Steve Aitken
During the initial , pre - garden phase of my soil improvement programme , I cope to bust up 10 inch of firmly - packed clay with interminable swings of my trustymattock . I spread compost over the surface of the beds an inch at a clip and rototilled it in . I was thrifty not to work the clay when it was too besotted , because the Great Compromiser worked wet can leave in some persistent clods , very reluctant in their willingness to ever come apart again . I render to shape the compost deep into the ground , and along with it , I added lime and phosphorus , the clay soil in my garden necessitate both . When surface - use , neither of these material moves down through the land , so incorporation to ample depth is very important to tolerate roots to grow into the subsoil . After 3 to 4 column inch of compost , I had the “ raised bottom ” I want . I called it quits ( for the clock time being ) and implant my garden .
In the years since , I have been back through most of the beds several times with the mattock and more compost , essay to get organic topic and lime incorporated deeply to break up the “ seal ” that forms between amend and unamended grunge , and to get my beds raised back up . It ’s promptly unmistakable that organic matter decomposes very quickly in the veggie beds . In spite of all the amendments , the beds no longer seem “ produce , ” and there ’s not much seeable grounds of all the compost I ’ve added . However , I can say by the coloring , now a dark brownness or else of red , and by the aggregation of the soil particle into a crumbly social organisation ( of a kin with umber background ) that humus is accumulating .
Reworking a bed is always a downslope practice when my rotation telephone for fall - planted garlic or when tater or root crops will be planted early the following leaping . I just ca n’t numerate on the bed being ironic enough in spring to influence the remains deeply without mess up up the complex body part I ’ve worked so hard to ramp up .

Cover crops keep on giving
Along with add compost , a 2nd strategy for tot up organic affair to my corpse soil is embrace cropping . I plant cover crops any time the beds in my garden would otherwise be unplanted or fallow . Fallow periods provide little additional organic biomass while set aside the decomposition of organic matter in the soil to continue . cover charge craw ply me with a variety show of services . They conduce to the advance in territory structure that I described earlier . They come down eroding and increment percolation . And they can smother weeds and even suppress weed source sprouting . Many cover crop will also suppress infective nematodes , for good example root gnarl nematode .
I take a matchet and scalp the cover harvest at the Earth’s surface , killing it but bequeath the biomass in place .
Leguminous cover crops can fix meaning amounts of atomic number 7 for use by subsequent crop . Through symbiotic affiliation with legumes , Rhizobia bacteria convert atmospherical atomic number 7 into an organic form that legumes use for growth . How much fixing depends on the length of the arise season , the local climate , and filth conditions . Nonleguminous cover crops , mainly grass or small grain , do not fix atmospherical N , but can be efficient in recycling residual stain N remain in the root zone at season ’s end , reducing leaching losses from the soil during the winter months . I often plant mixtures of grasses and leguminous plant in the drop to draw the benefit of both . This past fall I planted hairy vetch and cereal rye whisky , a proved mixture here . Crimson clover and rye whisky or oat also do well in my area .
In mid - May , I become a terminator , literally arrange these yearly plants down to prepare the bed for summertime vegetable . By then , the wintertime cover crops have allow for my yearly constitutive matter add-on , as well as enough nitrogen fertilizer to get my summer crop .
The less you disturb amended clay the better
Because of the many benefit that accrue to filth calibre , it is clearly in your myopic - term sake to incorporate constitutive matter on a regular basis and profoundly , at least when begin the process of slash a remains soil into shape . Soil particle aggregation and aggregate constancy , water holding capacity , drain , nutrient retention , and plant life root increment are all increased when organic matter is incorporated .
However , major losses in soil organic matter content can take place when the soil is inverted or mixed each year by tillage . Extensive tilth stimulates microbial activity ( afford the slight guy cable an appetite , so to speak ) , and the consumption of mass quantity of organic issue ensues . After your Lucius DuBignon Clay soil becomes more friable and you have provided a rich root zone for your garden plants , you should consider reducing tillage . flip-flop to a lower limit - till system increase soil constituent subject , territory organic atomic number 6 , full nitrogen , and soil microbial biomass carbon and atomic number 7 content , peculiarly at the surface and in the top 2 to 4 in . Because the soil remains undisturbed , fertilizers and other soil amendments do not become homogenized in the tillage layer . works bird feeder roots , therefore , incline to proliferate in the top 2 inch of fertile surface soil .
For a number of old age now , I have been experimenting with no - till vegetable planting in the spring . I take a liberal tongue ( i.e. , a matchet ) , ensure there are bandages available nearby , and scalp the covert crop at the Earth’s surface , kill it but leaving the biomass in place . I pull the residue apart just enough to compass a minor pickle with a trowel , unload in my tomato , white pepper , or melon transplant , and pull up the mulch back around the stem . I plant large seeds the same way , except that I leave behind a mulch - complimentary window for sunshine to impinge on the seedling when it emerge . For small - seed veg , I generally conjure the soil a bit more and leave a flight strip of mulch - innocent Earth’s surface above the seed .
Fruiting is detain a fleck because the ground is cooler for a fourth dimension , but overall production is not give . The mulch reduces weed growth and foreclose soil that may run overwintering disease pathogen from splashing up on foliage . Infiltration of irrigation water and rainfall improves , as does grease moisture retention .
The rest decompose much more slowly than if I tilled it in . Slower decomposition can result in more favorable timing of the dismissal of nitrogen from the leguminous plant cover crop .
A few sticky situations
There are a few context ask clay soils that merit extra consideration . In the western states , some clay soil contain excessive sodium ( these are do it as sodic soil ) . The surface assimilation of sodium by clay particles can cause aggregative Henry Clay particles to “ disperse , ” or amount aside , destroying crumbliness and tillage . Typically , the therapeutic to this problem is the incorporation of gypsum ( calcium sulphate ) to provide soluble atomic number 20 that can replace the adsorbed Na .
Unless gypsum is called for in a dirt test report card , however , it is rarely recommended as an amendment in stiff land . Most garden filth that have a right pH ( greater than 6.0 ) already contain adequate calcium .
Another special condition exists in those clay dirt that shrink when dry and swell when wet . It is critically crucial that any tilled land of these “ expanding mud ” soils ( and other clay soils , too ) fall out only when soil moisture conditions are those that Baby Bear would like : “ just correct . ”
To determine “ rightness , ” roll some grime between your palm into a ball about an inch in diam . The wet is right for tillage when a jot between thumb and finger causes the ballock of soil to break , stop , or dilapidate into piece .
Organic matter incorporate deep by farmland is particularly helpful in improving the soil body structure of flesh out clays .
A bank note of carefulness to gardener who would attempt to better clay soil by amend them with guts : This is a very risky business unless the sand ( often incorporated as much as 50:50 by volume ) is a very sharp sand . Otherwise , additions of sand to clay land can make a cementlike creature that hold out root emergence and block the stream of air and water .
