摘要

摘要22年来,CT卡梅尔山每年都会在肥沃的高地土壤上用橡树(Quercus velutina Lam.)或糖枫叶(Acer saccharum Marsh.)对地块进行改良。秋季施用后,叶片立即被掺入土壤中。将这些地块的12种不同蔬菜作物(生菜、辣椒、茄子、西红柿、毛豆、美味南瓜、意大利面南瓜、洋葱、韭菜、芸香、胡萝卜和豆类)的产量与未改良对照的产量进行了比较。所有地块都施用了等量的肥料。在任何处理之间,任何作物的蔬菜产量都没有显著差异,这表明每年施用未压实的叶子没有有害影响。一些土壤特性,如有机质和pH值在叶改地块上得到改善。研究表明,每年将树叶应用于农田(片状堆肥)是处理树叶的可行替代方案。

Cumulative Effect of Annual Additions of Uncomposted Oak and Maple Leaves on the Yield of Vegetables
ABSTRACT For 22 years, plots were amended annually with oak (Quercus velutina Lam.) or sugar maple leaves (Acer saccharum Marsh.) in Mt. Carmel, CT on a loamy upland soil. Leaves were incorporated into the soil immediately after application in the fall. Yields of 12 different vegetable crops (lettuce, peppers, eggplant, tomatoes, edamame, delicata squash, spaghetti squash, onions, leeks, rutabaga, carrots, and beans) from these plots were compared to yields from unamended controls. All plots received equal amounts of fertilizer. There were no significant differences in vegetable yields with any of the crops between any of the treatments indicating there are no deleterious effects of annual applications of uncomposted leaves. Some soil characteristics such as organic matter and pH improved on the leaf amended plots. Study shows that annual applications of leaves to cropland (sheet composting) is a viable alternative for the disposal of leaves.
