Effect of organo-mineral fertilizer and poultry litter waste on sugarcane yield and some plant and soil chemical properties

Abstract

Application of organic wastes in sugarcane (Saccharum officinarum) is an alternative possibly replacing or supplementing mineral fertilizers. This study aimed to evaluate the effects of poultry litter, organo-mineral fertilizer and mineral fertilizer on soil chemical properties, yield and plant content of macronutrients in sugarcane. The experiment was conducted at the Jalles Machado Mill in Goianésia-GO, from July 2009 to April 2010, as randomized complete blocks design (RCBD). The mineral fertilizer was applied at the following doses: 66; 120 and 82 kg ha -1 of N, P 2 O 5 and K 2 O, respectively; poultry litter and organ-mineral fertilizer were applied at doses of 3.0, 6.0 and 9.0 t ha -1 , in addition to the control (no fertilization). The following variables were analyzed: organic matter, macronutrients in soil and leaves and sugarcane yield. The productivity of sugarcane was higher with poultry litter and organo-mineral fertilizer in relation to mineral fertilization, and organo-mineral fertilization was superior to poultry litter. There was an increase in soil phosphorus levels in soil by fertilizing with poultry litter and organomineral fertilizer. Levels of soil K, Ca, Mg contents, acidity and soil organic matter, and levels of macronutrients in sugarcane did not change by the application of poultry litter and organo-mineral fertilizer comparing with mineral fertilizer. The use of organo-mineral fertilizer, as well as pure poultry litter is recommended.

Organomineral Fertilizer as Source of P and K for Sugarcane

“…Teixeira et al 16 also reported higher efficiency in stalk and sugar yield in plant cane using organomineral fertilizer at the highest rate, obtaining the same stalk yield with approximately 30 kg ha −1 less P 2 O 5 fertilizer. Ramos et al 17 also observed a higher stalk yield applying organomineral fertilizer compared to poultry litter and mineral fertilizer in plant cane, recommending it for sugarcane. Because of intense soil tillage for sugarcane establishment, the soil organic fraction is stimulated to mineralize and organomineral fertilizer or other organic sources, e.g., filter cake, can contribute to higher agronomic stability 31 as reflected in higher yields.…”

Chemical and technological characteristics of sugarcane as a function of pelletized organomineral fertilizer with filter cake or sewage sludge sources

“…In soils that receive sewage sludge organomineral plants accumulate more P than plants grown with only mineral fertilizers; the rate of P accumulation by the plants is influenced by the dynamics between climate and soil characteristics, especially in terms of the properties which determine the relationship between the proportion of adsorption and desorption of P from the soil [52]. The gradual P release is determined by the soil microbiota biodiversity and population present [53,54,4], and also by the residual effect of the fertilizer -organomineral fertilizers based on sugarcane filter cake can last for 4 years after its application [55,56].…”

“…The sugarcane filter cake is retained in rotary filters after sugarcane processing in industries and has been the main organic residue in the composition of organomineral fertilizers. Filter cakes were initially obtained only in the process of sugar production, but currently, the alcohol mills are producing considerable amounts of filter cake [4]. Good results of fertilization are being observed when filter cakes are applied to the soil (directly, or as organomineral), generating positive responses to the productivity of crops such as sugarcane [4][5][6].…”

Additionally, sugarcane filter cakes present about 70% moisture, high organic matter content, calcium, potassium, magnesium, nitrogen and about 1.2 to 1.8% of phosphorus; due to these characteristics, the use of filter cake in the composition of organomineral fertilizers has been increasing since 1999, when the prices of mineral fertilizers reached high levels and environmental demands by consumers started to gain more space [7].…”

Biochar e fertilizantes especiais no crescimento inicial da cultura do milho

“…Os fertilizantes organominerais que se originam de uma mistura a partir de fertilizantes orgânicos (origem animal e vegetal) e fertilizantes minerais, surgem como alternativa para a melhoria da eficiência das adubações sem comprometer o desenvolvimento da planta e o meio ambiente (RAMOS et al, 2017).…”
