摘要: Tests were made of the ability a leaching/mineralization model to predict amounts mineral N in soil spring as step towards estimating nitrogen fertilizer requirement sugar-beet crops. There was good agreement between predicted and measured values, both under conditions natural winter rainfall when covered prevent leaching. The also successfully leaching losses soon after drilling year which early season irrigation heavy rain induced considerable
