  • Performance of an optimized nutrient management system for double-cropped wheat-maize rotations in North-Central China

    Overapplication of N and P and insufficient supply of K are considered primary reasons for restriction of yield improvement in the North China Plain. Optimized nutrient management practices based on soil testing and yield targets have been developed. Other large scale field experiments have indicated that additional improvement for yield and nutrient use benefits is needed. The objective of this ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...

  • Crop sensors outdo farmers at choosing nitrogen rates

    Choosing how much nitrogen (N) to put on corn fields isn’t something farmers take lightly. Many factors go into the decision, including past experiences, the timing of application, yield goals, and results from soil tests. Nevertheless, crop sensors can select N rates for corn that outperform those chosen by farmers, according to more than 50 on-farm demonstration projects conducted in ...

  • Commercial greenhouse water demand sensitivity analysis: single crop case study

    Today water distribution utilities are trying to improve operational efficiency through increased demand intelligence from their largest customers. Moving to prognostic operations allows utilities to optimally schedule and scale resources to meet demand more reliably and economically. Commercial greenhouses are large water consumers. In order to produce effective forecasting models for ...

  • Development of a decision support system for small reservoir irrigation systems in rainfed and drought prone areas

    An integrated computer program called Cropping System and Water Management Model (CSWM) with a three-step feature (expert system—simulation—optimization) was developed to address a range of decision support for rainfed farming, i.e. crop selection, scheduling and optimisation. The system was used for agricultural planning with emphasis on sustainable agriculture in the rainfed areas through the ...

  • Nitrogen use efficiency and nitrogen uptake of juncea canola under diverse environments

    Nitrogen accounts for the largest energy input in oilseed production. Understanding N use characteristics of oilseed crops will help improve N use efficiency and minimize production costs. This study determined nitrogen use efficiency (NUE, defined as seed yield produced per unit of N supply), nitrogen fertilizer use efficiency (NFUE, defined as seed yield produced per unit of fertilizer N), and ...

  • Simulating yield response of quinoa to water availability with aquacrop

    The modeling of yield response to water is expected to play an increasingly important role in the optimization of crop water productivity (WP) in agriculture. During 3 yr (2004–2007), field experiments were conducted to assess the crop response to water stress of quinoa (Chenopodium quinoa Willd.) in the Bolivian Altiplano (4000 masl) under different watering conditions (from rain fed, RF, to ...

  • 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 ...

  • How green was my Vertical Farm?

    By 2050, 80% of the earth’s population will live in cities and 3 billion more people will need to be fed. The simple fact is we are running out of available land to grow enough food to feed them. If we can’t grow our cities outward to find more arable land, the only solution is to grow them upwards. This may change the way we design cities forever.The problem is real and immediate. Even by most ...

  • Agroecology can help fix our broken food system. Here’s how.

    The various incarnations of the sustainable food movement need a science with which to approach a system as complex as food and farming. This story was co-published with Food Tank, a nonprofit organization focused on building a global community for safe, healthy, nourished eaters. Thumb through U.S. newspapers any day in early 2015, and you could find stories on ...

  • Evaluating Microbiology of Compost

    The fact that not all compost is created equal has both producers and growers looking for ways to successfully evaluate compost quality. Traditional compost analysis has focused on NPK and micronutrient concentrations in an effort to mirror fertilizer analysis. Compost, however, is much more complex than fertilizer and its most significant value to the grower may be far more than its mineral ...

  • Redefining ag-wastes as coproducts

    Alan Doering doesn’t have the word “waste” in his vocabulary. As the scientist heading up the Agricultural Utilization Research Institute’s (AURI) coproduct utilization program, Doering sees crop residue, agricultural processing leftovers and biomass as products with value worth exploring. “Every leftover or coproduct has a value,” Doering says. “Our goal is to find the best use with the highest ...
