ABSTRACT Conservation agriculture principles applied to peanut can reduce soil erosion and production costs when cultivated in rotation with sugarcane. Still, the problem compaction is leading cause of skepticism about efficacy this practice. This research aimed study effect three management strategies compared conventional for cv. IAC-OL3, sugarcane using MEIOSI (method intercropping occurring...

Reduced tillage methods for field crop production result in less disruption of soil structure and often increased amounts of crop residue maintained on the soil surface. The combination of these two factors produces increased surface soil aggregation. This study was conducted in the field and within pots to determine whether surface residue by itself improves soil aggregation within a short per...

the objective of this study was to determine the quicker response of subsoil or surface soil to minimum tillage (mt) and conventional tillage (ct) and biofertilizers (bacillus coagulans, b), phosphorus fertilization (p) and integrated p and b (pb) under the wheat (triticum aestivum l vr. sardari) growing season. the experimental design was split plot laid out in randomized complete block design...

Subsoiling a compacted soil should loosen it, improve the physical conditions, and increase nutrient availability and crop yields. The aim of this work is to compare the effects of different tillage and fertility treatments in a loamy Typic Hapludoll soil, and to determine the interactions of N fertilization with several soil properties and dryland corn (Zea mays L.) productivity. The experimen...

Keller, T. 2004. Soil Compaction and Soil Tillage Studies in Agricultural Soil Mechanics Doctoral dissertation. ISSN 1401-6249, ISBN 91-576-6769-1 This thesis deals with various aspects of soil compaction due to agricultural field traffic, the draught force requirement of tillage implements and soil structures produced by tillage. Several field experiments were carried out to study the mechanic...

Mulching and tillage are widely considered to be major practices for improving soil and water conservation where water is scarce. This paper studied the effects of FM (flat mulching), RFM (ridge-furrow mulching), SM (straw mulching), MTMC (mulching with two materials combined), MOM (mulching with other materials), NT (no-tillage) ST (subsoiling tillage) and RT (rotational tillage) on wheat yiel...

A simple model is developed in which the density of weed seedlings emerging in a field is related to (1) the ability of seedlings to emerge from various depths in the soil, (2) the survival of seeds at different depths, and (3) the depth of seed burial in no tillage, rotary tillage, and plow tillage. Other tillage regimes are considered by analogy. Literature is reviewed to determine biological...

The objective of this research was to determine the influquire relatively large amounts of energy to develop ence of center-pivot sp...

Tillage practices are known to affect soil water retention, plant available and, consequently, crop production. Impacts can be determined by assessing hydraulic properties and characteristics. In this study, three tillage were investigated with respect vertical distribution development of soybean. A specific focus was set on determining evaporation transpiration as fractions evapotranspiration ...
