Response of wheat to gypsum soil conditioners
Keywords:Response of wheat, gypsum soil conditioners
This study was conducted in the greenhouse of the College of Agriculture and Forestry / University of Mosul during the agricultural season 1988-1989 to find out the effect of some locally available and economically inexpensive soil conditioners on the organic carbon and the carbon to nitrogen ratio of two types of gypsum soils cultivated with wheat with a high content of gypsum. 37 And others with a low gypsum content of 8% are located in the Shirqata region of Nineveh Governorate.
The results showed an improvement in the soil content of organic carbon and the ratio of carbon to nitrogen for the two types of soil when adding these conditioners, and the response of gypsum soils to nitrogen fertilization or when mixed with wheat straw in terms of their positive effect on the growth and production characteristics of wheat. As for the rest of the conditioners, despite their negative effects on growth and production characteristics, they recorded a positive effect on the soil organic carbon content and the carbon-to-nitrogen ratio of the two soils after the first season of cultivation.
