Last situation

If a compaction pan exists just underneath or near moldboard plow profundity, this hard pan can be disrupted by sub soiling to a depth of 16 to 18 inches to allow the development of a more extensive root system. Sub soiling also helps enlarge water infiltration. If there is an abundance of plants or plant residues on the soil exterior, diking or mowing follow by diking is usually advised prior to moldboard plowing. This should be done 6 to 8 weeks ahead of planting to bury residue and allow it to decay. straight away prior to plastic mulch setting up or transplanting, carry out final soil grounding and/or bedding with a rotary tiller, bedding disc or a double disc holler in combination with a bed covers press or leveling board. This provides a crestless, weed-free soil for the fixing of plastic mulch or the establishment of transplants.Tomatoes is usually transplanted into plastic mulch on raised beds. A raised bed will warm up more quickly in the spring and therefore will enhance earlier growth. Since tomatoes do poorly in excessively wet soils, a raised bed facilitates drainage and helps put off water logging in low areas or in poorly drained soils. Raised beds are generally 3 to 8 inches high. Keep in mind; however, that tomatoes planted on raised beds may also require more irrigation during drought conditions. Winter cover crops help protect the soil from water and wind erosion. When integrated into the soil as “green manure,” cover crops make a payment organic matter to the soil. Soil organic matter consists of plant and animal residues in various stages of decay. Organic matter improves soil structure (helps to reduce compaction and crusting), increases water infiltration, decreases water and wind erosion, increases the soil’s ability to resist leaching of many plant nutrients, and releases plant nutrients during decomposition.
