India ’s most wide accessible organic fertilizer is moo-cow dung manure . or else of sassy animal muck , use well - rot manure .

Using earthworms , manure , food wasteland , and green crop residues can be converted into forms that plants can use .
You should produce cover crop to nourish our territory , develop its fertility , and enhance its structure over time . Cover crops that have just been root out give nutrient already approachable to colly microorganisms and intellectual nourishment crop plant life . Cover crop also allow water and oxygen to permeate the soil via the cakehole create by their rot root . Cover crops , such as clovers , alfalfa , bean , and pea , are good because they convert atmospheric N into forms that crop plant can use .

hatch the soil with organic mulch . As a result of the mulch , the soil retains moisture and is better protect from temperature extremes . Mulch can be “ nibble ” by beneficial living beast such as microbes , earthworms , and others , and their dissipation will be progressively incorporate into the grunge ’s top layer . High - carbon mulch outlast elements that decompose rapidly in the soil food entanglement , make them more suited for weed suppression . During the growth time of year , reapply mulch .
The filth line should be at the source flare or tip if you dig a pickle that is broad enough for radical to thrive and deep enough for them to do so . Plants are stress , and their long - term health is jeopardized when planted too high or too deep . Break up any soil clump to avoid the formation of Brobdingnagian air pocket , which block the ontogenesis of ascendent . Afterward , fill up the quietus of the yap with soil and water it mildly to let it settle around the roots .
Do n’t apply your foot to push down the soil since this might damage some of the roots . Upon nail the hole ’s backfilling , make a grease berm or levee with a acme of several in by manufacture a broad bowl . This will help to trap water over the roots until the plant can suck it .
