An inexpensive balance for measuring throughfall in cereals
暂无分享,去创建一个
Abstract The construction and electronics of a balance designed to measure throughfall in the inter-row of cereal crops with a resolution of less than 0.1mm of water, are described. The field performance is assessed and results from three days are used to obtain the amount of rainfall intercepted by a wheat canopy with complete ground cover. The measurements required to obtain the saturation capacity of the canopy are discussed.
