The present invention is particularly concerned with practices for conserving soil nitrogen and for supplying the soil hitrogen requirements for plant nutrition. These practices nvolve the employment, as active agent, of novel butane compound having the formula:
wherein X is a hydrogen atom or a
R group; R is a hydrogen atom or a C1-Ck alkyl or
group wherein each Y is independently a hyd- 1rogen, chlorine, bromine, or fluorine atom or a methyl group and Z is a straight or branched chain C1-C4 alkyl group R' is a C1-C4alkyl or C1-C4 alkoxy group or a halogen atom and isO or an integer of 1 or 2.
本发明特别涉及保护土壤氮素和提供植物营养所需的土壤氮素的方法。这些做法包括使用具有以下式子的新型
丁烷化合物作为活性剂:
其中 X 是氢原子或
其中 X 是氢原子或 R 基团;R 是氢原子或 C1-Ck 烷基或
R'是 C1-C4 烷基或 C1-C4 烷氧基或卤素原子,并且是 O 或 1 或 2 的整数。
