Top Dressing Fertilizer in Western Canada
Western Canada has a short growing season which makes another pass for top dressing fertilizer sometimes difficult to achieve. Many crops have the fertilizer applied during the seeding season with Liquid Distribution Systems, (like these kits we make here). Often this will meet the crops fertilizer requirements for the whole season. Making one pass makes sense in a season that brings the right ...

Accounting for adaptation in assessing impact of climatic variations on crop yields: an empirical study of Arizona
The goal of this paper is to analyze the impacts of climatic variation around current normals on crop yields and explore corresponding adaptation effects in Arizona, using a unique panel data. The empirical results suggest that both fertilizer use and irrigation are important adaptations to climate change in crop production. Fertilizer use has a positive impact on crop yields as expected. ...

Influence of urea fertilizer placement on nitrous oxide production from a silt loam soil
Received for publication April 8, 2009. Urea placement in band or nests has been shown to enhance N use efficiency, but limited work has been done to assess its affect on N2O emissions. This study compared N2O emissions from urea prills applied to an Amsterdam silt loam (fine-silty, mixed, superactive, frigid Typic Haplustolls) using broadcast, band, and nest placements. Experiments were ...

N-(N-butyl)thiophosphoric triamide/NBPT
Urease inhibitor is a kind of substance that can inhibit the activity of soil urease, and it is a new technology which has been studied in urea or nitrogen compound fertilizer. Using soil urease inhibitor can effectively slow decomposition of urea into ammonia process, reduce soil NH4 + and NH3 concentration, soil fertility and crop fertilizer synchronization. NBPT is the most effective inhibitor ...

In-situ soil moisture conservation: utilisation and management of rainwater for crop production
The salient results of in-situ soil water conservation technologies that have been found suitable for increasing soil moisture in the arid and semiarid lands of eastern Kenya are reviewed. The results showed that Zai pits, tumbukiza and deep tillage when used together with soil fertility improvement can increase crop yields by 4–10 times in comparison to conventionally cultivated fields. ...

Seed yield and yield stability of chickpea in response to cropping systems and soil fertility in northern latitudes
Improved cultural practices are required to enhance the adaptability of chickpea (Cicer arietinum L.) in northern latitudes. Field experiments were conducted to determine the effects of cropping systems, cultivar choices, and soil fertility on the stand establishment, seed yield, and yield stability of chickpea in northern latitudes. Four cultivars were tested in no-till barley (Hordeum vulgare ...

Nitrogen storage with cover crops and nitrogen fertilization in tilled and nontilled soils
Improved crop and N management practices are needed to increase soil N storage so that N fertilization rate and the potential for N leaching can be reduced in tilled and nontilled soils. We examined the influence of cover crops and N fertilization rates on N inputs from cover crops, cotton (Gossypium hirsutum L.) and sorghum [Sorghum bicolor (L.) Moench] and soil total N (STN) content at the 0- ...

Seed yield and yield stability of chickpea in response to Cropping Systems and soil fertility in Northern Latitudes
Improved cultural practices are required to enhance the adaptability of chickpea (Cicer arietinum L.) in northern latitudes. Field experiments were conducted to determine the effects of cropping systems, cultivar choices, and soil fertility on the stand establishment, seed yield, and yield stability of chickpea in northern latitudes. Four cultivars were tested in no-till barley (Hordeum vulgare ...

How to Improve Production Efficiency of Organic Fertilizer Production Line
Organic fertilizer, with its unique advantages like high nutrition content, easy-to-get raw materials and environmental friendly, is becoming more and more popular for fertilizing crops and plants, and many organic fertilizer processing factories appear at the same time. It’s obvious that their purpose is to gain more profits from organic fertilizer production, and the main problem they ...

Processing organic fertilizer by using crop straw
The crop straw organic fertilizer production line is advanced composting fermentation process, inoculates high-speed and high-efficiency fermentation bacteria, which makes the straw cellulose rapidly decompose and transform, and all kinds of pathogenic bacteria, weed seeds and aphid eggs are killed, and produce the bio-organic fertilizers with strong stability and full range of nutrient. We ...

Soil organic carbon after twelve years of various crop rotations in an aridic boroll
Eliminating summer fallow or establishing perennial grass elicited measurable gains in soil organic C (SOC) after just 6 yr in a crop rotation study on an Aridic Boroll in southern Alberta. This study was resampled after 12 yr to determine if SOC increases were continuing with time and to evaluate the impact of alternative crop rotation and fertilizer treatments on SOC. The crop rotation ...

Necessity of the development of new organic fertilizer equipment
1. The necessity of developing new organic fertilizer. Fertilizer is one of the decisive factors for the high yield and quality of grain. The use of fertilizer has made a great contribution to the increase of crop production and the alleviation of food shortage. Fertilizer plays a very important role. In the past, the fertilizers used by people were relatively single, lacking fertilizers for ...

Injection method of fertilization (Cultan technology)
Dosage of liquid fertilizers Liquid mineral fertilizers have already proven their advantages over granular fertilizers, these namely are prolonged action and maximum absorption of the active substance. So here is the question, what is the most effective way of using liquid fertilizers? Taking into consideration the reasons for transition to soil fertilizers, agronomists and farmers often point ...

Change in Surface Soil Carbon under Rotated Corn in Eastern South Dakota
A diversified crop rotation may reduce fertilizer N inputs for corn (Zea mays L.) and increase soil organic C (SOC). Our objectives were to determine the effects of crop rotation and fertilizer N on soil C within the surface soil (0–15-cm depth). Rotations were started in 1990 on a Barnes sandy clay loam near Brookings, SD. Measurements of SOC began in 1996. Primary tillage since 1996 was chisel ...

Top 10 Advantages of Organic Fertilizers for Agriculture and Farming
Fertilizers supplement the nutrients already present in the soil. The fertilizing products can be vaguely classified as Organic or Natural Fertilizers and Synthetic or Man-Made Fertilizers. While synthetic or chemical fertilizers are concentrated, strong and quick enough to dissolve in the soil immediately, Organic Fertilizers for plants release nutrients slowly with time and often contain many ...

Direct steam distillation as an alternative to the illinois soil nitrogen test
Development of the Illinois Soil N Test (ISNT) has rejuvenated the search for a soil-based N test to measure potentially mineralizable soil N. Accurate quantification of amino sugar N has been achieved using the ISNT, but issues concerning sample variability and analysis time have led to the discovery of a 10 mol L–1 NaOH direct steam distillation (DSD) procedure. Our primary objective was to ...

Detailed introduction of three fertilizer production lines: disc, drum and double roller
When many customers purchase fertilizer production equipment, there are many choices and inquiries about the three production lines: disc granulator production line, drum granulator production line and double roller granulator production line. Many people don't understand the principles of these fertilizer production processes and the specific equipment. In fact, a set of fertilizer production ...

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 ...
