Assessing the economic benefits and costs of conservation tillage
The economic benefits of the adoption of conservation tillage depend on site-specific factors, including soil characteristics, local climatic conditions, cropping patterns, and other attributes of the overall farming operation. While it is possible to draw some general inferences about components of economic returns and costs, a comprehensive assessment of the net private benefits from greater ...

Field Scouting Apps Boost Efficiency, Speed
Scouting is one of the most critical services that ag retailers and consultants can offer their grower-customers. The need for accurate information about crop conditions, including weeds, insects and other pests, has never been greater. [Related: 17 Field Scouting Apps For Precision Agriculture] There’s a lot riding on a successful scouting program. Improved yields and higher profits are ...

Production of dryland barley for human food: quality and agronomic performance
Grain β-glucan content is the most important attribute for barley (Hordeum vulgare L.) varieties destined for the human food market. This trait is important because of the blood glucose and cholesterol-reducing properties of β-glucans. High levels of grain protein content, test weight, and seed size and endosperm color may also add value. Seed yield potential, in part, determines the ...

Fertilizer vs. organic matter contributions to nitrogen leaching in cropping systems of the Pampas: 15N application in field lysimeters
Abstract Nitrogen (N) export from soils to streams and groundwater under the intensifying cropping schemes of the Pampas is modest compared to intensively cultivated basins of Europe and North America; however, a slow N enrichment of water resources has been suggested. We (1) analyzed the fate of fertilizer N and (2) evaluated the contribution of fertilizer and soil organic matter (SOM) to N ...

Climate change impacts on regional maize yields and possible adaptation measures in Argentina
In this work, the impact of future climate (2081-2090) on regional maize yields was assessed through a crop simulation model. The climatic inputs correspond to the regional model MM5/CIMA, considering grids of 50 km * 50 km. Crop model runs were done under typical crop management conditions with and without considering the fertilisation effect of CO2. Without CO2 effects, the impact of future ...

Strategies to improve nitrogen use efficiency in winter cereal crops under rainfed conditions
Developing fertilizer strategies that increase nitrogen use efficiency (NUE) could reduce unnecessary input costs to farmers and environmental impact of N losses. Two field experiments were performed in northern Spain to evaluate alternative N fertilization strategies to improve NUE in winter cereal crops (wheat [Triticum aestivum L.] and barley [Hordeum vulgare L.]). The strategies were: (i) ...

Are we creating our own Easter Island?
For centuries environmental destruction in human history has been littered with civilizations that failed because humans exploited natural resources. Examples of over consumption of natural resources can be found from around the world — from the Incas to the Middle East. Currently, the human population is about 6 billion and will rise to 9 billion in the year 2050. That’s a growth rate of 80 ...

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, ...

Winter wheat and maize response to urea ammonium nitrate and a new urea formaldehyde polymer fertilizer
Slow release N fertilizers have potential to improve yield and nitrogen use efficiency (NUE) in winter wheat (Triticum aestivum L.) and maize (Zea mays L.). A slow release urea formaldehyde polymer (UFP) was compared with aqueous urea ammonium nitrate (UAN) [(NH2)2CO, NH4NO3] during a 2-yr field experiment in North Carolina. Crops were grown on Candor (sandy, siliceous, thermic Grossarenic ...

Understanding Soil Sensor Readings, Interpreting Data for Better Decision-Making
Background:Soil sensors have become an important tool in precision agriculture, enabling farmers to monitor soil conditions and make informed decisions about plant growth and management. However, proper interpretation of soil sensor readings is essential to ensure accurate and effective decision making. This paper explores the importance of understanding soil sensor data and how it can be ...

Thiamethoxam: Assessing flight activity of honeybees foraging on treated oilseed rape using RFID technology
This study was designed to assess homing behaviour of bees foraging on winter oilseed rape grown from seed treated with thiamethoxam (as Cruiser OSR) with one field drilled with thiamethoxam treated seed and two control fields drilled with fungicide‐only treated seed. Twelve honeybee colonies were used per treatment group, 4 each located at the field edge (on‐field site), at approximately 500m ...

Measurement of Total Carbon in Soil and Compost by TOC Solid Sample Measurement System
Soil contains a large amount of organic matter such as plant residue that can be decomposed by microorganisms. This organic matter plays a key role in plant growth by maintaining good chemical and physical conditions in soil and is useful in improving and stabilizing the productivity of agricultural crops. Compost, a type of fertilizer in which organic matter is decomposed by microorganisms, ...

AquaCrop—The FAO crop model to simulate yield response to water: III. Parameterization and testing for maize
The first crop chosen to parameterize and test the new FAO AquaCrop model is maize (Zea mays L.). Working mainly with data sets from 6 yr of maize field experiments at Davis, CA, plus another 4 yr of Davis maize canopy data, a set of conservative (nearly constant) parameters of AquaCrop, presumably applicable to widely different conditions and not specific to a given crop cultivar, was evaluated ...

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, ...

Validating the FAO aquaCrop model for irrigated and water deficient field maize
Accurate crop development models are important tools in evaluating the effects of water deficits on crop yield or productivity. The FAO AquaCrop model predicts crop productivity, water requirement, and water use efficiency (WUE) under water-limiting conditions. A set of conservative parameters [calibrated and validated for maize (Zea mays L.) in a prior study and considered applicable to a wide ...

The manage database: nutrient load and site characteristic updates and runoff concentration data
The 'Measured Annual Nutrient loads from AGricultural Environments' (MANAGE) database was developed to be a readily accessible, easily queried database of site characteristic and field-scale nutrient export data. The original version of MANAGE, which drew heavily from an early 1980s compilation of nutrient export data, created an electronic database with nutrient load data and corresponding site ...

Monitoring for the golden balance
On Herøya in Porsgrunn, Yara has an ammonia plant, three nitric acid plants and a calcium nitrate plant. Together the plants produce a wide range of fertilizers that meet the requirements for fertilization of crops under varying climatic conditions and on different soils. Half of the production at Porsgrunn goes to overseas markets, mainly in Asia. The rest goes to Europe. – Our ...

Climate change, a storm in the coffee cup
Coffee is the third most consumed beverage in the world after water and tea. Food and Agriculture Organization (FAO) confirms ‘Coffee is the most widely traded tropical product, with up to 25 million farming households globally accounting for 80 per cent of worlds output’. In 2020, 87% of the global coffee production originated from the top 10 biggest coffee-producing nations, says ...
