Crop productivity and economics during the transition to alternative cropping systems
Many environmental benefits accrue from reducing tillage and increasing crop diversity; however, economic factors often encourage the continued use of intensive tillage and specialized crop production. This study examined crop yields, input costs, and economic returns during the transition to a range of cropping system alternatives in the northern Corn Belt region, including different system ...

The Effect of Off-farm Work on the Intensity of Agricultural Production
Changes in agricultural production methods have been associated with environmental pressure and a loss of natural habitats. This paper explores the extent to which farmer participation in off-farm work (an increasing phenomenon in most developed countries) changes the intensity of agricultural input use focusing, in particular, on fertilizer and crop protection product use. A sample selection ...

Look to Ag leader to help you comply with new Dicamba rules and regulations
Sometimes, rules and regulations come along to change how you manage your farm. The federal government’s recent action on the common herbicide ingredient dicamba is one such example, and resilient farmers may need to make some changes to comply with new regulations laid out by the U.S. Environmental Protection Agency (EPA) in October 2017. That’s when EPA ruled that three crop ...

Soybean response to inoculation and nitrogen application following long-term grass pasture
Current demand for soybean grain [Glycine max (L.) Merrill] may lead to a conversion of pasture and Conservation Reserve Program fields into soybean or corn (Zea mays L.) production. Our objective was to determine the effect of soybean seed inoculation with Bradyrhizobium spp. and fertilizer N application rate on soybean productivity planted 1 and 2 yr after conversion to row crop production. ...

Cover crop and nitrogen effects on maize productivity in no-Tillage Systems of the Brazilian cerrados
Cover crops in direct seeding mulch-based cropping (DMC) systems can be an effective tool to optimize N management for crop production in the Brazilian cerrados. The objective of this study was to determine the effect of four cover crops on maize (Zea mays L.) grain yields in two fields that had been under DMC for 3 and 14 yr. We hypothesized that cover crops would optimize N supply to the maize ...

Regional Analysis of use Patterns of Plant Protection Products in Six EU Countries
Abstract This study followed a review conducted by LEI-DLO in Phase 1 of the project on possibilities for future EU environmental policy on plant protection products (PES-A). In their review LEO-DLO suggested three avenues for investigation: Areas of more than moderate use of plant protection products: Germany - Nordrhein Westfallen, Rheinland Pfalz, Berlin France - Champagne-Ardennes, ...

Sentera FieldAgent Analytics Toolset Expands to Include Tassel Counts
Tassel Counts available for the 2020 growing season Sentera announces that its Tassel Count analytics product will be available to all FieldAgent™ customers in March 2020. Instead of forecasting yield using a small number of spot samples, the Sentera tassel count analytics tool allows users to more precisely calculate yields using tassel population data gathered across the entire field. ...

Possibilities for Future EC Environmental Policy on Plant Protection Products
Abstract This report presents the results of a study to examine and evaluate the economic, environmental and social benefits of plant protection products (PPPs) in agriculture with the main emphasis on the economic aspects. The approach followed was to carry out four case studies - each covering a single crop in a specific region of major production-comparing standard, integrated and organic ...

Ontario Horticulture Research Priority Report 2016
Sector Consultation The Ontario Fruit and Vegetable Growers Association partnered with Vineland to host a research strategy workshop in November 2014 with the goal of defining the top five research priorities for each crop group. Grower organizations were invited to nominate two representatives to participate on their behalf and a number of researchers from relevant fields were invited to ...

Irrigation challenges in the sub-humid US Mid-South
Irrigated area in the Mid-South USA continues to increase and now totals four million ha. Because of low available water holding capacities and shallow root-limiting layers in many soils, irrigation management is difficult. Water quality and water use efficiency impacts under irrigation are poorly understood, but comprehension is necessary if conversion from groundwater to surface water supplies ...

What nutrients are left in your soil?
Knowing, not estimating , means better soil health and profitability Farming in Western Canada means working in a climate of extremes–hot or cold, wet or dry. It’s a conundrum that drives agriculture innovation, new technologies and precision agronomy practices on behalf of Prairie farmers that’s appreciated around the world. Last year, many farmers worked to deal with extreme ...

An overview of preharvest factors influencing postharvest quality of horticultural products
Postharvest product quality develops during growing of the product and is maintained, not improved by postharvest technologies. Available genetic material allows discrimination of external and internal quality attributes that must satisfy consumer requirements and indulgences. Farmers face challenges in utilising technologies for producing high quality crops; meaningful manipulation of light, ...

Lessons learned from potato growers down-under
Andy Alexander, specialist potato consultant and agronomist, has provided advice across the UK and Australia for over 35 years, and has travelled to the southern continent over 17 times. He explains how adapting to change in a volatile climate has been key to success for growers in Australia, and what lessons UK growers can take from this. “My role is to provide business advice, measuring ...

Plants Activate `Wartime` Protein Production to Fight Invasion
Plants are constantly attacked by bacteria, viruses and other pathogens. When a plant senses a microbial invasion, fundamental changes occur in the chemical soup of proteins inside its cells, the workhorses of life. In a new study published in Cell, Duke University researchers have uncovered a key ingredient in plant cells that reprograms their protein-making machinery to fight disease. Crop ...

Integrating winter annual forages into a no-till corn silage system
The benefits of cover crops within crop rotations are well documented, but information is limited on using cover crops for forage within midwestern United States cropping systems, especially under no-tillage management. Our objective was to evaluate plant, animal, and soil responses when integrating winter cover crop forages into no-till corn (Zea mays L.) silage production. Three cover crop ...

Losing Soil
In 1938, Walter Lowdermilk, a senior official in the Soil Conservation Service of the U.S. Department of Agriculture, traveled abroad to look at lands that had been cultivated for thousands of years, seeking to learn how these older civilizations had coped with soil erosion. He found that some had managed their land well, maintaining its fertility over long stretches of history, and were ...

Watering Scarcity: Private investment opportunities in agricultural water use efficiency
This report was prepared by Rabobank in collaboration with the World Resources Institute. In many regions around the world, demand for fresh water now outstrips renewable supplies. Water scarcity is projected to worsen considerably due to a combination of factors such as population increase, higher incomes and changing lifestyles, pollution, and climate change. Agriculture is by far the biggest ...

Uncovering your Farm’s Hidden Yield Potential
What are you missing in your harvest data? Across hundreds or even thousands of acres, it’s easy to get lost in this sea of data points. It’s simply too much for one person to calculate. That’s what makes a digital tool a powerful ally. It never gets tired or distracted and when provided the right data, it never puts a decimal in the wrong place. The yield analysis tool in ...

Chemical-free disinfection of seeds for maximum yield
Seeds are the starting point for the majority of our food. Vegetables, cereals, fruits and many, many more products start as small seeds. It is no surprise that the seed market has kept growing over the past few years. In fact, the seed market is projected to grow even more, with a CARG of 3,4% from 2017 to 2023. Safe and delicate disinfection of seeds is a must in order to produce a healthy and ...
