Based on geostatistical theory, 1,054 soil sites were selected from the surface (0–20 cm) of the typical black soil area in Northeast China. The spatial structure of soil pH, alkali‐hydrolyzed N, effective P, and available K was investigated using Kriging and spatial statistics. The soils...
Tree growth and soil nutrient levels were studied in a southern Illinois strip-mined area. Heights of black walnut, yellow-poplar, silver maple, and osage orange underplanted in a black locust plantation were greater than on shortleaf pine plots. Using plant bioassay techniques, soil from the ...

2003). On average, about half of the reactive-N applied as fertilizer is incorporated into crops consumed by humans or feed for livestock; the other half may cycle through various forms in the soil but is eventually mostly released into the atmosphere or aquatic systems (Smil 1999, 2001; ...
aHealthy soil provides water and nutrients to plants and encourages healthy plant growth. Allow plenty of time to prepare your soil for planting. As noted by the Cornell University Department of Horticulture, if you want to plant a vegetable or flower garden, begin to prepare your soil the fal...
Zinc (Zn) deficiency in soils and crop plants is a global concern, undesirably influencing crop productivity, crop quality and human health. Farmers add Zn to soil through different agro-inputs by various means, which influences its behaviour in soil-plant systems. Efficient soil Zn management ...
