Exchangeable basic cations and nitrogen distribution in soil as affected by crop residues and nitrogen
(Brazilian Archives of Biology and Technology, 2011-06-01)
In this work, a greenhouse experiment was conducted to study the effects of N fertilization and residues of pearl millet, black oats and oilseed radish on pH and Ca, Mg, K, NO3-, and NH4+ distribution within the profile ...

Fig trees (Ficus carica L.) leaf nutrients contents with potassium fertilization
(Univ Federal Lavras-ufla, 2005-05-01)
Potassium rates were evaluated in fig trees cv Purple of Valinhos during first development years. The experimental design was in randomized blocks with four replications and six treatments. The plots were splited in the ...
Nitrogen and potassium fertilization affect apple fruit quality in southern Brazil
(TAYLOR & FRANCIS INC, 2008)
Nitrogen (N) and potassium (K) are usually found in higher concentrations than other macronutrients in apple (Malus x domestica Borkh) fruits and are most frequently associated with changes in fruit quality. The aim of ...

Impacts of limestone and nitrogen top dressing application on the potassium content in the soil profile and marandu-grass leaf concentration
(Sociedade Brasileira de Zootecnia, 2009-07-01)
Objetivou-se avaliar os efeitos de nitrogênio (0, 100, 200, 300 e 400 kg/ha.ano), com ou sem aplicação de calcário dolomítico em cobertura, sobre o teor de potássio (K) do solo nas profundidades de 0 a 5; 5 a 10; e 10 a ...
