“…For the other evaluated depths there was no significant difference between the subplots. These results are different from those presented by Torres & Pereira (2008). After evaluating the dynamics of potassium in crop residue cover crops in the 'Cerrado' , these authors observed that the bread grass showed the highest release rate, increasing the K content in the soil.…”

“…However, the effectiveness of the no-tillage system is related, among other factors, to the quality and quantity of straw produced by cover crops, the persistence of these residues over the soil, the rate of decomposition and nutrient release (Torres & Pereira, 2008).…”

“…A TR do K pelas plantas variou entre 21 e 33 % do K adicionado; os maiores valores ocorreram no tratamento com NPK mineral (Figura 4) e naquele com cama de aves constituída por areia. A pequena variação na TR do K entre os tratamentos foi em razão da forma como o K está nas camas de aves, totalmente disponível para as plantas, não necessitando ser mineralizado (Torres & Pereira, 2008;Pitta et al, 2012).…”

“…Potassium contained in vegetable residues is easily released, as it is not part of the composition of any organic compound or directly dependent on microbial action for decomposition, a result of its high solubility and ease migrating to the soil (ROSOLEM et al, 2006(ROSOLEM et al, , 2007PEREIRA, 2008). The release of potassium from organic matter, according Rosolem, Calonego and Foloni (2003), depends more on the frequency and intensity of rainfall.…”
