25. STRUCTURAL PROPERTIES OF SOIL IN MAIZE AND FORAGE GRASS INTERCROPPING UNDER NO-TILLAGE IN THE BRAZILIAN CERRADO
ABSTRACT Integration of forage grasses with grain crops, such as maize, allows maintaining soil cover. The objective of this study was to evaluate the tensile strength, friability, and stability of soil aggregates in the maize and forage grass intercropping under no-tillage system. The study used a completely randomized block design with seven treatments and

26. Timing and growing conditions of nitrogen topdressing influence the grain yield and protein content of four wheat cultivars
ABSTRACT The application of an adequate rate and splitting of nitrogen is essential for wheat grain yield and protein content. The aim of this work was to adjust nitrogen management approaches regarding agronomic performance and protein content of wheat cultivars in various environments. Field experiments were conducted under no-tillage system on soybean mul

28. Applying the NDVI from satellite images in delimiting management zones for annual crops
ABSTRACT: The utilization of Normalized Difference Vegetation Index (NDVI) data obtained through satellite images can technically improve the process of delimiting management zones (MZ) for annual crops, resulting in socio-economic and environmental benefits. The aim of this study was to compare delimited MZ, using crop productivity data, with delimited MZ u

29. Boundary line approach applied among crop emergence parameters and soil physical properties
RESUMO A técnica “boundary line” foi proposta para interpretar dados biológicos, onde uma variável é uma resposta biológica e a outra uma variável independente. O objetivo do trabalho foi correlacionar parâmetros de emergência de milho e soja com propriedades físicas da cama de semeadura do solo aplicando o procedimento “boundary line”. O es

30. Biochemical and Biological Properties of Soil from Murundus Wetlands Converted into Agricultural Systems
ABSTRACT The implementation of conservationist systems that improve soil properties and reduce the impacts of the conversion of native areas is fundamental for feasible agricultural exploitation. This study aimed to evaluate the impact on soil biological properties caused by the conversion of murundus fields into agricultural systems and verify the ability o

31. Carbon indices to assess quality of management systems in a Subtropical Acrisol
ABSTRACT: Management systems to improve soil quality are essential for agricultural and environmental sustainability. We assessed the quality of soil management systems applied to a subtropical Acrisol in terms of the carbon management index (CMI), the stratification ratio for total organic carbon (SR-TOC) and light fraction of organic matter (SR-LF). In add

32. Decomposition and Nutrient Release of Cover Crops in Mango Cultivation in Brazilian Semi-Arid Region
ABSTRACT Knowledge of the decomposition dynamics of aboveground phytomass and its release of nutrients in mixtures of cover crops as well as the impact on the soil tillage system is fundamental for the sustainable management of agroecosystems. This work aimed to evaluate whether soil tillage and the choice of cover crops cultivated in the interrows can be te

33. SOIL PHYSICAL ATTRIBUTES AND PRODUCTION COMPONENTS OF SUGARCANE CULTIVARS IN CONSERVATIONIST TILLAGE SYSTEMS
ABSTRACT Machine traffic and conventional tillage can cause structural degradation of the soil, affecting the physical attributes and, consequently, the production and longevity of the sugarcane field. The objective of this study was to evaluate the production components of sugarcane cultivars (RB965902, RB985476, RB966928, RB855156, RB975201, RB975242, RB03

34. Nitrous Oxide Emissions in No-Tillage Onion ( Allium cepa L.) Crops Are Increased by Oilseed Radish Cover Crop and Poultry Manure Application
ABSTRACT The use of cover crops and poultry manure (PM) is an alternative to reduce the use of synthetic inputs and can contribute to the nutrient cycling in onions ( Allium cepa L.) grown under a no-tillage system. However, this management practice may contribute to an increase in N2O emissions to the atmosphere. The aims of this study were to evaluate the

36. Soil mesofauna in consolidated land use systems: how management affects soil and litter invertebrates
ABSTRACT: Soil mesofauna consists of small invertebrates that live in the soil or litter and are sensitive to climatic conditions, management systems, plant cover and physical or chemical soil attributes. These organisms are active in the cycling of nutrients, since they fragment the organic matter hereby accelerating microbial decomposition. The aim of this
