Winter cover crops affecting physical and chemical soil attributes in a commercial vineyard

Ciência Rural, 2017
: Cover crops may have direct or indirect effects on the physical and chemicalsoil attributes; these cropsplay a key role in the cycling of nutrients in the soil and add labile organic carbon, bringing economic and environmental benefits to the system ...

IDENTIFICATION OF AGRONOMIC MANAGEMENT UNITS BASED ON PHYSICAL ATTRIBUTES OF SOIL [PDF]

Journal of soil science and plant nutrition, 2011
Oil palm (Elaeis guineensis Jacq) is an alternative for the development of productive systems in the tropics. By determining the spatial variability of physical characteristics of soil, specific recommendations for certain areas within a zone can be made.

Sugarcane filter cake application to coffee crop and soil physical attributes

Revista em Agronegócio e Meio Ambiente, 2021
Filter cakes are solid organic byproducts of the sugarcane industry that are generally used as fertilizers for crops such as coffee. Filter cake application has improved soil chemical, physical and microbiological attributes, especially for weathered soils.

Prediction of water retention of soils from the humid tropics by the nonparametric k-nearest neighbor approach [PDF]

, 2013
Nonparametric approaches such as the k-nearest neighbor (k-NN) approach are considered attractive for pedotransfer modeling in hydrology; however, they have not been applied to predict water retention of highly weathered soils in the humid tropics ...

Chemical, physical, and biological attributes of the soil in integrated systems

Brazilian Journal of Science, 2023
Integrated systems are conservationist and sustainable systems with great prominence on the national scene for reducing financial and productive risk in the agricultural sector and reducing environmental damage. One of the successes of these systems is to see the cultivation environment in an integrated way, knowing each of its components; soil, plant,

Soil physical attributes and corn yield as affected by soil managements and fertilization

, 2022
No-tillage system is an efficient technique in control of soil erosion, when compared with conventional tillage, however, some studies indicate higher compaction under no-tillage, mainly in the surface layer. Strategies that increase the organic matter content, as crop rotation and organic fertilization, can be used to solve the soil compaction.

SOIL PHYSICAL ATTRIBUTES BEFORE AND AFTER MANAGEMENT UNDER SOWING FORWARD SPEED [PDF]

Engenharia Agrícola, 2019
ABSTRACT The soil management system affects physical attributes, and the forward sowing speed can increase or decrease its results. Thus, this work aimed to evaluate management systems before and after soil mobilisation and forward sowing speed on soil physical attributes.

Effect of management systems in soil physical attributes

, 2007
Inadequated soil tillage can induce the formation of compacted layer near soil surface. Soil physical attributes were assessed after sixteen years of distinct soil management on a typical dystrophic red latosol located in Passo Fundo, Rio Grande do Sul State, Brazil.
