Soil fertility gradually declines over time and under continuous cultivation. It negatively reflects on the yield and quality of crop production, including guava, which is a perennial fruit of high economic potential. ...

The sweet potato is an important food for the population, being rich in proteins, fibers, nutrients such as K, P, Ca, Mg, Fe, Mn, Cu, and bioactive compounds. It is usually cultivated by small producers. In Brazil, the ...

The objective of this work was to evaluate rates for applications of water treatment sludge (WTS) as a nutrient source for grasses and leguminous plants cropped in a soil degraded by tin mining in the Amazon Region (Natural ...

Some evidences indicate that N-fertilization of crops decreased pH values of loess soils of the Argentinean Pampas in the last decades. We analyzed the A-horizons of four N-fertilized (F) and non-fertilized (NF) paired ...
