(Faema-fac Educacao & Meio Ambiente, 2017-07-01)
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 ...
Biomass Accumulation and Nutritional Requirements of Potato as Affected by Potassium Supply
(2020-09-01)
Potassium (K) supply affects the growth and tuber yield of potato (Solanum tuberosum L.) as well as the uptake and removal of certain nutrients. However, information on this is scarce or inconsistent. Thus, this study was ...
Potassium Leaching as Affected by Soil Texture and Residual Fertilization in Tropical Soils
(Taylor & Francis Inc, 2010-01-01)
