Conifer growth stimulation and forest management

摘要

Conifer growth is stimulated by topical and/or foliar application of biuret which achieves direct contact of biuret with the conifer roots and/or foliage respectively. Foliar application is more effective on older trees. Optionally, undesired vegetation, such as ferns and broad- leaf plants, is controlled and conifer growth is promoted by application of biuret-containing solutions to the foliage of all plants. Novel compositions particularly useful in these methods contain biuret and a surfactant and/or polar solvent other than water sufficient to facilitate foliage wetting.
