Mulches soil improvers

Garden compost can be classified as a medium-fertility soil improver (see pp.34-35). Apply it where required at an average rate of around 25 gal/50 sq ft (100 liters/5 sq m). This is a layer of approximately V2 in (1 cm) thick spread out evenly over the ground. Apply compost in spring or summer as a mulch, or dig it into the top 8 in (20 cm) of the soil. 

Leaf mold can generally be used as a low-fertility soil improver (seepp.34-35) and a moisture-retaining mulch after one year. It should be darker and more crumbly than the newly fallen leaves, but does not have to be fully rotted. For a finer product, for use in seed and potting mixes or as a topdressing for... 

Leaf mold and other low-fertility soil improvers these are beneficial preceding root crops. Apply anywhere as a mulch to improve structure, especially over winter. 

Crops in this family all prefer fertile soil that does not dry out easily. They are often included in the "roots" section of a rotation, in soil that has been improved for a previous crop. They may appreciate a mulch of a medium-fertility soil improver on poorer soils. Spinach beet... 

If the soli has been prepared appropriately in advance, most crops should not need extra feeding. Long-term crops may benefit from mulching with a medium- or high-fertility soil improver. 

Mulching bare soil reduces water loss through evaporation and prevents germination of weed seeds. If a high- to medium-fertility soil improver is used, this also adds plant nutrients. Apply mulches to warm, moist soil in spring and summer. 

Bulky soil improvers spread over vegetable beds to condition and feed the soil applying water correctly at the roots of plants, rather than pouring it over the leaves the need for hoeing is reduced in these close-planted beds shallots growing through a mulch membrane for moisture retention and weed control. 

Select a suitable blueberry type for your zone highbush (Zones 4-7), lowbush (Zones 2-6), midhigh (Zones 3-7), or rabbiteye (Zones 7-9). Buy two- or three-year-old container-grown plants that are not rootbound. You will need to test the pH of your potting mix or any compost you use for soil Improvement to be certain that it is not alkaline. Use only rainwater when watering plants. Plant bushes In late fall or early winter, spacing them 5 ft (1.5 m) apart. Mulch with composted bark or pine needles. 

What to do Improve the waterholding capacity of soil. Mulch soil. 

Compost is used as (organic) fertilizer, soil improver/conditioner, manufactured topsoil, growing medium, and mulch for use in [25] ... 

Several applications based on biodegradable plastics that end up directly in soil after their useful life are under development and experiencing rapid market growth. Examples are mulch films, strings, hooks and clips, slow release pheromone dispensers and drip irrigation pipes. Furthermore, mature industrial compost, obtained from a feedstock that includes biodegradable polymers, also ends up in soil because of its application as a soil improver. 

No deleterious effects of either the wheat mulch or tillage were observed on soybeans (Table V) or corn (data not presented). In general, crop growth was better in mulched or no-till plots. Enhanced soil moisture in the mulched treatments and reduced morningglory densities in the non-tilled treatments may have contributed to improved crop growth. 

Holes can be cut to allow planting through the membrane as appropriate. Membranes may be covered with a loose mulch, to hold them in place, extend their life span, and improve their appearance. A mulch membrane must be permeable, to allow air and water into the soil, unless it is only to be kept in place for a few months. However, to suppress the more vigorous perennial weeds (see also pp.80-81), the membrane may need to be in place for several years while there are several biodegradable choices of membrane material, a nonbiodegradable material is the more practical option in such situations. 

Conservation agroecosystems developed in the Great Plains of the U.S. to control soil erosion are characterized by the presence of varying quantities of plant residues on the soil surface. This residue mulch protects the soil from the erosive forces of wind and water, resulting in improved stream water quality and soil conservation. Conservation tillage systems also help maintain soil productivity and reduce energy requirements of crop production (15). However, crop yield reduction has been observed with conservation wheat production in some areas of the U.S. (16-18) and with rice culture in the Far East (, 20).
