EFFECT OF CONSERVATION AGRICULTURE ON YIELD AND PROTECTING ENVIRONMENTAL RESOURCES [PDF]

open access: yesAgroLife Scientific Journal, 2015
Conservative soil tillage (minimum tillage and no-tillage) are considered among the most important components of conservation agriculture. Their research and extension was imposed especially in hilly areas with specific problems of desertification ...

Reduced‐Port Versus Multi‐Port Laparoscopic Colectomy for Colorectal Cancer: A Systematic Review, Meta‐Analysis, and Meta‐Regression

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
Reduced‐port laparoscopic colectomy (RPLC) for colorectal cancer offers modest intraoperative benefits, including shorter operative time and lower blood loss, while maintaining comparable postoperative recovery, lymph node yield, and complication rates to multi‐port laparoscopic colectomy (MPLC).

Relevance of the irrigation and soil management system to optimize maize crop production under semiarid Mediterranean conditions

open access: yesAgricultural Water Management
Irrigation system and soil management through the different tillage system may have a significant impact on maize crop performance due to their capabilities to modify soil water content and soil physical and biochemical properties.

THE SUBSIDY FOR ADOPTING CONSERVATION TILLAGE: ESTIMATION FROM OBSERVED BEHAVIOR [PDF]

open access: yes
Due to payoff uncertainties combined with risk aversion and/or real options, farmers may demand a premium in order to adopt conservation tillage practices, over and above the compensation for the expected profit losses (if any).

Herbicide sorption, degradation, and leaching in three Swedish soils under long-term conventional and reduced tillage

open access: yes, 2009
Soil tillage has the potential to influence water flow and solute transport through the soil by cutting continuous macropores which connect the soil surface to the subsoil.

Balancing Exploration and Exploitation Through a Sequential Hybrid of Roach Infestation and Mayfly Algorithms for Constrained Engineering Design Optimization

open access: yesAI &Innovation, EarlyView.
ABSTRACT Maintaining an effective balance between exploration and exploitation is essential during optimization processes, from mathematical functions to more complex problems such as constrained engineering design optimization, particularly when addressing highly nonlinear issues with numerous local optima and strict feasibility requirements.

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Economies of Size for Conventional Tillage and No-till Wheat Production [PDF]

open access: yes
Production costs and economies of size for both conventional tillage and no-till wheat production were determined. The reduction in the price of glyphosate after the patent expired improved the relative economics of no-till for continuous monoculture ...

Redistributive land reforms, agricultural productivity, and structural change: New cross‐national evidence

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Large‐scale land reforms constitute a substantial redistribution of wealth and reallocation of agricultural land, which is a major form of asset and production input in developing countries. While land redistribution (from the rich to the poor) remains a highly controversial issue, extensive evidence on its effect is limited.
