ABSTRACT - The objective of this work was to investigate changes in soil chemical characteristics, phosphorous concentrations in maize leaves, and the agronomic efficiency (AE) of magnesium thermophosphates produced from rocks of the Maicuru complex in the Brazilian Amazon Basin, in comparison with triple superphosphate (TSP). The thermophosphates consisted of a mixture of raw material from apatite, dunite, and quartz sandstone from Maicuru, aiming to adjust the contents of P, Mg, and Si. The mixture was melted, ground, and subjected to the analysis of solubility, chemical characteristics, and granulometry. The experiment consisted of two rates of dolomitic lime (0 and 2.4 Mg ha-¹), three rates of P (20, 60, and 100 mg kg-¹ soil), and four sources of P (TSP and three Mg thermophosphates), as well as of two control treatments, with and without lime. Three replicates were carried out per treatment in pots containing plants of the BR 5107 maize hybrid. Phosphorous concentration was determined in maize leaves at 45 days after sowing. The Mg thermophosphates showed a high AE and a higher neutralizing effect with the application of lime, which improved soil chemical characteristics and AE. The thermophosphates obtained from rocks of the Maicuru complex can be an alternative P fertilizer in maize production. RESUMO- O objetivo deste trabalho foi investigar mudanças em atributos químicos do solo, concentrações de fósforo em folhas de milho e eficiência agronômica (EA) de termofosfatos magnesianos produzidos com rochas do complexo de Maicuru, na bacia da Amazônia brasileira, em comparação ao superfosfato triplo (SFT). Os termofosfatos consistiram de mistura de matéria-prima de apatita, dunita e arenito quartzoso de Maicuru, para ajuste dos conteúdos de P, Mg e Si. A mistura foi fundida, moída e submetida à análise de solubilidade, características químicas e granulometria. O experimento consistiu em dois níveis de calcário dolomítico (0 e 2,4 Mg ha-¹), três níveis de P (20, 60 e 100 mg kg-¹ de solo) e quatro fontes de P (TSP e três termofosfatos magnesianos), além de dois controles, com e sem calcário. Foram realizadas três repetições para cada tratamento, em vasos com plantas de milho do híbrido BR 5107. A concentração de P foi determinada nas folhas de milho aos 45 dias após a semeadura. Os termofosfatos magnesianos apresentaram alta EA e maior poder neutralizante com a aplicação de calcário, o que melhorou as características químicas do solo e a EA. Os termofosfatos obtidos de rochas do complexo Maicuru podem ser alternativa de fertilizante fosfatado na produção de milho.

ABSTRACT. Integrated Crop-Livestock Systems (ICLS) are being considered to improve food production sustainability and are of increasing interest to the modelling community worldwide. Our goal was to evaluate the ability of an agroecosystem model simulator (ECOSMOS) to predict plant growth and yield, and water dynamics in an ICLS in the Western region of São Paulo State, Brazil. Four fields of approximately 50 ha each were monitored after the implementation of the ICLS at the end of 2018. Soybean yields (two seasons), mixed-pasture aboveground dry biomass and soil water content (for the pasture only) measurements were contrasted with predictions from ECOSMOS with recently implemented soybean and pasture sub-models. Preliminary results from a generic simulation for the whole farm showed that the model was able to capture fairly well the seasonal variation in growth and water dynamics. Such results suggest that the existing knowledge and modelling approaches embedded in the model are robust. Future steps toward modelling the ICLS will involve to parameterise the model for Brazilian cultivars of the system using data from controlled/manipulative experiments, develop a framework to simulate two plants concomitantly, and then assess its capability to predict environmental variables of interest, such as carbon dynamics. |
