Traditional tree-integrated farming systems are adopted for the security of food, fodder and fuelwood. Therefore, investigations were carried out to study the leaf litter, wood litter, miscellaneous litter and total litterfall in Eucalyptus based agri-silvicultural system. In this manuscript we observed that the leaf component was the main contributor to the total above-ground biomass in all the planting spacings followed by woody and miscellaneous. The major nutrient pool was in the leaves, and branches . Whereas, the total return of nutrients during both the years study period was in 6×1.5 m spacing returned the highest amount of N (54.04 kg/ha) through leaf litter followed by 3×3 m spacing (53.05 kg/ha), 17×1×1 m spacing (52.85 kg/ha) in 2014-15. Out of which the total amount of these nutrients used by the intercrops was 44.01 (kg/ha) of nitrogen, 9.96 (kg/ha) phosphorus and 68.65 (kg/ha) of potassium respectively. Hence, the remaining amount 45.31 (kg/ha) of nitrogen and 7.05 (kg/ha) of phosphorus. During seven and eighth year of Eucalyptus planted at 3×3 m spacing the farmers can take barley as an intercrop with the Eucalypts terticornis with a spacing of 3×3 m without adding any additional amount of nitrogen and phosphorus into the system. Hence can save some additional cost of fertilizer, which otherwise they have to add to raise intercrops with Eucalyptus.

不同间隔下基于桉树的传统农林业系统的土壤和植物养分收支估算

为了保护粮食，饲料和薪柴的安全，采用了传统的树木综合种植系统。因此，进行了调查以研究桉树叶的凋落物，木材凋落物，杂物凋落物和总凋落物。基础的农林系统。在这份手稿中，我们观察到在所有种植间隔中，木质成分和其他成分之后，叶片成分是总地上生物量的主要成分。主要的养分池在叶子和树枝上。而在这两个研究期间，养分的总返回量是在6×1.5 m间距下，通过凋落物返回的氮量最高（54.04 kg / ha），其次是3×3 m间距（53.05 kg / ha），17 2014-15年度×1×1 m间距（52.85 kg / ha）间作所使用的这些养分的总量分别为氮44.01（kg / ha），磷9.99（kg / ha）和钾68.65（kg / ha）。因此，剩余量为氮45.31（kg / ha）和磷7.05（kg / ha）。在桉树的第七年和第八年以3×3 m的间距种植，农民可以将大麦与3毫米3 m的桉树作为间作，而无需向系统中添加任何额外的氮和磷。因此可以节省肥料的一些额外成本，否则必须增加以增加与桉树间作的肥料。
