Изобретение относитс  к сельскому хоз йству, в частности к препаратам, предотвращающим потери азота удобрений из почвы в результате денит- рисЬикации и выщелачивани .The invention relates to agriculture, in particular to preparations that prevent the loss of nitrogen from manure from soil as a result of denitration and leaching.

Цель изобретени  - повышение эффективности ингибирующего действи  состава.The purpose of the invention is to increase the effectiveness of the inhibitory effect of the composition.

Пример. В реактор (V 2 л), снабженный мешалкой и холодильником, загружают соответствующие количества 2-метил-3-этилпиридина щавелевокислого , 2-метШ1-5-зтилпириднна iид- рохлорида и воду, затем к полученному раствору добавл ют соответству- .ющее количество К-оксида/2-метилпи- рщпша. Реакционную массу выдерживают в течение 5 ч при комнатной температуре .Example. The appropriate amounts of 2-methyl-3-ethylpyridine oxalate, 2-methyl-1-methyl-pyridine hydrochloride and water are loaded into a reactor (V 2 l) equipped with a mixer and a cooler, then the appropriate amount of K is added to the resulting solution. -oxide / 2-methylpirshcha. The reaction mass is maintained for 5 h at room temperature.

Испытание провод т в лабораторных услови х на выщелоченном черноземе . Дл  этого почву, просе нную через сито с диаметром отверстий 3 мм, увлажн ют до 60% от полной влагаемкости . В увлажненную почву добавл ют мочевину кристаллическую из расчета 200 мг азота на 1 кг почвы и состав дл  ингибировани  в дозах 1, 10 и 20% от веса внесенного азота удобрений. Смесь (.почва+состав дл  ингибировани +мочевина) тщательно перемешивают , набивают в стекл нные сосуды и инкубируют в термостате при 25°С. Образцы дл  анализа отбирают через 7, 14, 21 и 35 дн. Аммиачный азот определ ют реактивом Несслера, нитратный азот - ионселек- тивным электродом на потенциометре ОР-211.The test is carried out in laboratory conditions on leached chernozem. For this, the soil sifted through a sieve with a hole diameter of 3 mm is moistened to 60% of the total moisture capacity. Crystalline urea is added to the moistened soil at the rate of 200 mg of nitrogen per 1 kg of soil and the composition is inhibited in doses of 1, 10 and 20% of the weight of fertilizer applied by nitrogen. The mixture (soil + inhibitor composition + urea) is thoroughly mixed, packed into glass jars and incubated in a thermostat at 25 ° C. Samples for analysis are taken after 7, 14, 21 and 35 days. Ammonia nitrogen is determined by Nessler reagent, nitrate nitrogen is determined by an ion-selective electrode on an OR-211 potentiometer.

Действие состава в 1,5 раза эффективнее по сравнению с известным ингибитором .20% of the weight of nitrogen applied by urea inhibits the nitrification of nitrogen fertilizers in the soil for 35 days. and reduces the loss of urea nitrogen from the soil as a result of denitrification and leaching. The effect of the composition is 1.5 times more effective compared with the known inhibitor.
