“…Esse resultado indica que houve efeito residual da adubação fosfatada, realizada na safra 2009/ 2010, o que pode ser explicado pela condução dos experimentos em sistema plantio direto, o qual proporciona aumento do teor de MO e maior atividade da microbiota do solo (Souza et al, 2010), além de o pH do solo estar corrigido e essas condições interferirem no processo, reduzindo a fixação de P e aumentando seu efeito residual. Sousa & Lobato (2003) também constataram efeito residual e apresentaram dados de recuperação de 35 a 62% do P aplicado, após 13 colheitas de milho, em Latossolo argiloso de Cerrado, utilizando, como fonte, o superfosfato simples, em doses variáveis, aplicadas a lanço, de uma única vez, ou, parceladas, no sulco.…”

Residual effect of monoammonium phosphate coated with different polymers on maizeThe use of phosphate fertilizers coated with polymers can reduce losses by phosphorus fixation in the soil, providing the element for a longer period of time. The objective of this study was to evaluate the residual effect of phosphorus rates and forms of monoammonium phosphate coated with different polymers on production components and grain yield of maize in the first and second harvest. The experiment was conducted in Selvíria -MS, in a loamy Oxisol. A randomized block design in a 4 x 4 factorial scheme with four repetitions was used in the experiment: four P 2 O 5 rates (0, 50, 100 and 150 kg ha -1 ) applied at sowing, in four forms: conventional monoammonium phosphate and monoammonium phosphate coated with three different polymers. To evaluate the residual effect of these treatments on the maize successor crop, the new crop was sown in the same line of the previous crop. The residual level of phosphorus in the soil increased linearly up to 150 kg ha -1 P 2 O 5 . The MAP coated with polymers showed the same residual effect of

“…However, despite the promising results described by Moreira et al (2010) with the application of cattle manure, by Miranda et al (2005) with lime, and with both products by Souza et al (2010), few studies have reported the positive effects of this management practice on crop yield and soil chemical properties.…”

Most tropical soils have high acidity and low natural fertility. The appropriate application of lime and cattle manure corrects acidity, improves physical and biological properties, increases soil fertility, and reduces the use of chemical and/or synthetic fertilizers by crops, such as soybean, the main agricultural export product of Brazil. This study aimed to assess the effects of the combination of the application of dolomite limestone (0, 5, and 10 Mg ha −1 ) and cattle manure (0, 40, and 80 Mg ha −1 ) on grain yield and the chemical properties of an Oxisol (Red Latosol) cultivated with soybean for two consecutive years. The maximum grain yield was obtained with the application of 10 Mg ha −1 of lime and 80 Mg ha −1 of cattle manure. Liming significantly increased pH index, the concentrations of calcium (Ca 2+ ) and exchangeable magnesium (Mg 2+ ), and cation exchange capacity (CEC) of soil and reduced potential acidity (H + + Al 3+ ), while the application of cattle manure increased pH level; the concentrations of potassium (K + ), Ca 2+ , and exchangeable Mg 2+ ; and CEC of the soil. During the 2 years of assessment, the greatest grain yields were obtained with saturation of K + , Ca 2+ , and Mg 2+ in CEC at the 4.4, 40.4, and 17.5 levels, respectively. The results indicated that the ratios of soil exchangeable Ca/Mg, Ca/K, K/Mg, and K/(Ca+Mg) can be modified to increase the yield of soybean grains.

“…Outro fator que pode ter contribuído para essa deficiência seria a precipitação do P do solo com o cálcio, formando compostos de baixa solubilidade, devido a elevação do pH provocada pelo cálcio do fosfato natural e os altos teores de cálcio e magnésio contidos nos insumos orgânicos aplicados (Tabela 1), além disso o solo apresentava teor médio de fósforo, o que pode ter contribuído para adsorção de parte do P existente na matéria orgânica aplicada (SOUZA et al, 2010). Por outro lado, os teores adequados de N e K na matéria seca foliar se devem aos teores desses elementos contidos nos estercos aplicados, o que é confirmado por Lazcano; Gómez-Brandón e Dominguez (2008) Santos et al (2001) e Nascimento et al (2002).…”

RESUMO -No período de agosto de 2009 a julho de 2010 foi desenvolvido um experimento em um pomar de pinheira (Annona squamosa L.), no município de Remígio, PB com o objetivo de avaliar os teores de macro e micronutrientes no tecido foliar das plantas em solo com esterco bovino e cama de frango. Os tratamentos foram distribuídos em blocos casualizados, com parcelas subdivididas no tempo, com três repetições e duas plantas por parcela, em esquema fatorial 2 × 5 × 2, referente a duas fontes de matéria orgânica de origem animal (esterco de bovino e cama de frango), cinco doses de matéria orgânica em volume (0,0; 3,5; 5,3; 7,1 e 8,9%) e duas épocas de avaliação das plantas aos 36 e 48 meses após o transplantio. As doses de matéria orgânica foram definidas com base no teor de matéria orgânica de cada fonte. Com exceção de magnésio e zinco, as fontes de matéria orgânica não diferiram estatisticamente sobre os teores dos demais nutrientes na matéria seca foliar das plantas. A maior acumulação de nutrientes na matéria seca das folhas da pinheira ocorreu na amplitude das doses entre 6,01 e 8,65% de matéria orgânica. Palavras-chave: Fruta do conde. Esterco bovino. Cama de frango.ABSTRACT -From August 2009 to July 2010, an experiment was conducted in a sugar-apple orchard (Annona squamosa L.) in the town of Remigius PB, in order to evaluate the levels of macro and micronutrients and the leaf tissue of the plants in a soil treated with cattle manure and poultry litter. The treatments were distributed into randomized blocks, with plots split with time, three replications and two plants per plot, in a 2 × 5 × 2 factorial arrangement, corresponding to two sources of organic matter of animal origin (cattle manure and poultry litter), five doses of organic material by volume (0.0, 3.5, 5.3, 7.1 and 8.9%), and two periods of plant evaluation, 36 and 48 months after transplanting. The doses of organic material were set based on the organic-matter content of each source. With the exception of magnesium and zinc, the organic-matter sources did not differ statistically from the levels of other nutrients in the leaf dry-matter of the plants. The greatest accumulation of nutrients in the leaf dry-matter of the sugar apple was in the dosage-range of between 6.01 and 8.65% of organic matter.
