Shading screens for the improvement of the night time climate of unheated greenhouses
|
The objective of this work was to study the effect of shading screens, normally used during the day for cooling purposes, on the night-time climate of unheated greenhouses. For this purpose, first a number of experimental measurements were taken during cold nights to characterise the greenhouse...

Residue Management and Cultural Practices
|
High crop residue levels translate directly into soil conservation benefits. Most experts believe the most effective conservation tillage practices leave at least 30 percent residue after planting. Residue burial or removal for biomass harvest should be tempered with conservation benefits. When...

No-tillage and high-residue practices reduce soil water evaporation
|
Reducing tillage and maintaining crop residues on the soil surface could improve the water use efficiency of California crop production. In two field studies comparing no-tillage with standard tillage operations (following wheat silage harvest and before corn seeding), we estimated that 0.89 and 0...

Environmental and Agronomic Benefits of Aromatic and Medicinal Plant Strips for Rainfed Almond Orchards in Semiarid Slopes (SE, Spain)
|
In the Mediterranean zone semi-natural vegetation and diverse mountain-cropping systems have been converted into monocultures with low tree densities, leaving the soil unprotected. Soil loss and runoff over a three-year period were monitored in hillside erosion plots (35% slope and 144 m2 in...

Crop Rotations on Organic Farms
|
For a variety of other reasons that we will explore in this publication, crops can and should be managed in rotations. No one disputes the fact that rotations are beneficial. The use of two- and three-year rotations by the majority of the grain farmers in this country shows they agree that yields...

Cover Crops for Soil Improvement in Horticultural Crops
|
Cover crops maintain and improve soil health. They prevent soil erosion and increase organic matter, improving micro- biotic activity, soil structure, and water infiltration rates. Cover crops also aid in nutrient cycling, reduce soil temperature fluctuations, provide habitat for beneficial...

Cover Crops for Organic Farms
|
Cover crops are pivotal parts of every organic farmer’s management scheme. They are crucial to the main goals of building soil health and preventing soil erosion. Cover crops are also important tools for increasing fertility and controlling weeds, pathogens, and insects in organic crops. In...

Managing Alternative Pollinators: A Handbook for Beekeepers, Growers, and Conservationists
|
This book could not have come at a better time. We stand at a crossroads, where honey bee losses and rental rates for pollination are on the rise, research is expanding our knowledge of native bees’ role in crop pollination, and growers are looking for pollination alternatives to improve...

Atrazine Use and Weed Management Strategies to Protect Surface Water Quality
|
Atrazine can be applied to the soil surface either before or after planting, incorporated into the soil prior to planting, or sprayed on corn and weeds, postemergence. Knowing that atrazine moves predominately in solution (dissolved in water) versus attaching to soil particles aids our...

Intercropping of Annual Foodcrops
|
Maintaining soil fertility is often one of the main challenges in agricultural production. Intercropping is one of the options available to maintain soil fertility and crop yields. Other benefits of intercropping are risk spreading, weed control and the decrease of pest and disease incidence. In...
