Examining Sulfur Rates for Wheat and Split Application versus a Single Broadcast
نویسنده
چکیده
Traditionally, sulfur responses have been limited to coarse textured or other soils low in organic matter that have little potential for sulfur mineralization. In the past, the burning of fossil fuels has contributed a significant amount of sulfur through deposition in rain. Also, many phosphorus fertilizers contained sulfur as impurities, which lessened the need for the application of sulfur to soils. However, a sharp decrease in the amount of sulfur applied by atmospheric deposition has been observed since about 1980 and fertilizers have become more refined such that less incidental sulfur applications are being made. With higher yielding environments becoming more common with many crops and with high commodity prices, farmers are questioning whether sulfur is a limiting nutrient in their fields and if fertilizer sulfur is needed to maximize yields. With fertilizer prices on the increase, determining what situations warrant application and what source should be applied is important to maximize the amount of crop response for each dollar spent on fertilizer.

Examining Sulfur Rates for Wheat & Split Application versus a Single Split Broadcast
Decreased additions of sulfur to the atmosphere through low sulfur diesel fuel and reductions in industrial emissions have lead to a decrease in incidental deposition of sulfur for crops. This has left some to question if sulfur needs to be supplied to most crops as fertilizer. Current recommendations for sulfur fertilizer applications in Minnesota are limited to sandy soils with low organic ma...

Due to unsuitable soil physical conditions, calcareous soils, and the existence of a huge amount of sulfur in the country, the study of sulfur effects on the soil structure and other soil properties is necessary. Therefore, the effects of different rates of sulfur including: 0, 750, 1500 and 3000 kg/ha, when accompanied by Halothiobacillus neapolitanus bacteria, on the soil properties in the co...

Mineral nitrogen (N) fertilization in cereals is commonly split into three or four applications. In order to simplify N fertilization, a single N application either broadcast or placed on the soil surface was compared to conventionally split fertilization for winter wheat (Triticum aestivum L.). The 4-year experiment (2007-2010) was performed using a participatory approach on farmers' fields on...

To study the effect of zinc sulfate rates on response of bread wheat cv. Cahmran to terminal heat stress conditions in Ahvaz, Iran, this experiment was conducted at the research farm of Agricultural and Natural Resources Sciences University of Khuzestan, Iran in two cropping cycles (2015-2016 and 2016-2017). The experimental design was split plot arrangements in randomized complete block design...
