Mechanized harvesting of a Pinus taeda L. forest does not impair the physical properties of a Nitossolo Bruno
HIGHLIGHTS The physical properties of the Nitossolo Bruno showed small changes between the pine forest area and the post-harvest forest area. Mechanized harvesting in the forest area does not compromise the soil water properties to a depth of 40 centimeters. The Nitossolo Bruno maintains its structural integrity even after the forest mechanical harvesting operations. ABSTRACT […]
Nutrient uptake and removal by runner peanut cultivars of different maturity groups
HIGHLIGHTS Late-maturing cultivar had higher biomass yield, uptake, and removal of nutrients. The uptake peak of B and K occurred between stages R5 and R6. Despite the high rate of K uptake, only 22% is removed. Approximately 70% of the N uptake by peanuts is removed. ABSTRACT Modern runner-type peanut cultivars have high yield potential, […]
Macrofauna and soil properties in agroforestry system and secondary forest
HIGHLIGHTS Genotypes of Saccharum Complex differ in growth response upon bacterial inoculation. Agroforestry systems enhance soil health in fragile soil. The management in agroforestry systems is favorable for soil macrofauna. Soil fauna can act as a soil quality indicator in agroforestry systems. ABSTRACT Atlantic Forest devastation has resulted in the search and introduction of management […]
Initial growth response of twelve Saccharum Complex genotypes to inoculation using Nitrospirillum viridazoti
HIGHLIGHTS Genotypes of Saccharum Complex differ in growth response upon bacterial inoculation. S. spontaneum was the genus with a higher growth response. Initial growth of 12 genotypes showed a limited response to bacterial application. Under low soil fertility, the order of macronutrient accumulation was K >> N > Ca > Mg > P. ABSTRACT Sugar […]
Automatic measurement of surface runoff at the plot scale
HIGHLIGHTS Prototypes with a tipping bucket system were developed and calibrated The equipment automatically measures surface runoff The resolution of the devices can reach 5 L pulse -1. The equipment is capable of monitoring flows of up to 80 L min -1. The equipment is inexpensive and easy to build and maintain. ABSTRACT Although the hydrological importance of water […]
Effect of potassium rates and application methods in no-till on soil K availability and crop yield
HIGHLIGHTS The critical soil test level of K for southern Brazil is overestimated. The band-application of K increases the soybeans and wheat grain yield. The critical soil test value of K to achieve 90% soybean yield is 64 mg dm-3. Fertilization recommendations should consider the soil layer of 10-20 cm. ABSTRACT The combination of potassium […]
Delineation of potential management zones for cowpea by factorial kriging and spatial Fuzzy C-Means of yield and soil chemical and texture properties
HIGHLIGHTS Maps of soil properties alone were not efficient in delineating management zones Factorial kriging analysis can be used in cokriging to estimate soil properties Factorial kriging and sFCM were efficient in delineating the two management zones Is possible to solve problems of multiple soil property maps with FK and SFCM ABSTRACT In precision agriculture, accurate […]
Saturated hydraulic conductivity and steady-state infiltration rate database for Brazilian soils
HIGHLIGHTS Mean values of hydraulic properties are presented for different soil classes and soil textural groups Fine textured tropical Brazilian and temperate soils reveal relevant differences in Ksat values An open database with soil hydraulic properties for Brazilian soils is presented ABSTRACT Soil saturated hydraulic conductivity (Ksat) and steady-state infiltration rate (SSIR) are essential and […]
