messages on yield and soil quality •After one cycle, spring wheat grain yields higher after pea and N fixers than most other mixes. •Higher cover crop biomass correlated with lower spring wheat yield, likely b/c of more water and N use. •Relatively few soil health differences between pea and 8-species mix after one cycle; not unexpected. from book Plant, Soil and Microbes: Vol. 1 Implications in Crop Science Effects of Pesticides on Environment Chapter December with , Reads.
Soil water dynamics. Surface water runoff is simulated for daily rainfall using the SCS curve number equation Subsequently, soil water infiltration is computed using the Green-Ampt model The process of soil water redistribution was incorporated into the model using the Richard’s equation as described by Šimůnek et al.

Rainfall in the Big Spring area was limited and poorly distributed. The most productive and reliable crops were cotton and sorghums. Yields of maize and winter wheat were unsatisfactory. Good yields were obtained from groundnuts, but the lack of a crop residue after harvesting allowed considerable wind erosion to take place during March and : F.

The analysis shows soil to be a key determinant of corn and soybean area in the regions studied. Building Soils for Better Crops is a one-of-a-kind, practical guide to ecological soil management, now expanded and in full provides step-by-step information on soil-improving practices as well as in-depth background—from what soil is to the importance of organic matter.
After arriving in Big Spring, Texas he was in charge of the research program on wind erosion and dryland crop production systems.
He developed methods for estimating crop damage by wind erosion to determine if and when damaged crops should be replanted. From this research the acreage replanted declined from 75% in to less than 25% in Most studies of the influence of weather and climate on food production have examined the influence on crop yields.
However, climate influences all components of crop production, includes cropping area (area planted or harvested) and cropping intensity (number of crops grown within a year).

In Illinois, the greatest concern for soil deg-radation is erosion caused by water. All of these practices depend on soil type, soil texture, and slope as well as on the crops that are grown.

Going south towards Lubbock, the dominant crop shifts to cotton and the soil color begins to lighten with an observable reddish tint that becomes dominant on the way to Big Spring.
Wheat and other cool‐season crops drop out of the rotation because the spring temperature and precipitation patterns do not match. Book Collections.

The crop is tolerant of a soil pH as low as and saline conditions. Because of its tolerance to salinity, canola has been used as the first crop on newly drained dikes in the Netherlands. Canola requires approximately 16 to 18 inches of water through its growing season, with 8 to inches used by annual varieties in July near flower and.Alfred E.
Hartemink, in Advances in Agronomy, B. Funding and Scope. Throughout past decades funding opportunities for fundamental soil research have been reduced (Mermut and Eswaran, ), and much soil research is externally funded with a strong problem-solving this trend soil science has returned to where it started: little fundamental .Winter cover crops should be established as early as possible, or at least four weeks before the average date of the first hard freeze (Clark, ).
Soil temperatures for planting should be between 45– 85°F. In northern climates, spring-planted crops generally produce less aboveground biomass and root growth, and are less.
