Prospects for the use of calcium ammonium nitrate on acidic soils of the Non-Black Earth Area

The results of the effectiveness application calcium ammonium nitrate (CAN) in winter wheat crops “Moskovskaya-39” variety on dark-gray forest, heavy-loamy soil Ryazan region is presented. advantage CAN-a a universal form nitrogen fertilizer, which has neutral reaction and creates optimal conditions for feeding plants with zone its application, where main mass plant roots located, revealed. Along nitrogen, fertilizer contains magnesium, are essential formation productivity, exchange carbohydrates proteins. In field experience soils not saturated bases, were obtained, indicating physiologically showed an over acidic - ammonia nitrate. Dynamics productivity sowing that area leaves reached maximum sizes by flowering phase 61.6-76.6 cm 2 /plant, largest value indicator 76.6 /plant was variant use CAN at dose 54 kg/ha nitrogen. provided reliable increase harvest grain comparison experiment 63.7 67.1 cents per hectare, statistically close values yield variants using doses 68 3.8-5.3% respectively. creation during growing season accompanied improvement quality grain,
