Organic fertilization has been proposed as an alternative approach to supply nutrients for crops, in the frame of organic and sustainable agriculture, with aim decrease high inorganic rates, protect environment production costs farmers. Since different types fertilizers, such manures, olive mill wastewater (OMW), sewage sludge (SS), crushed pruning wastes, composts cover exist soil amendments i...

The present study was conducted to evaluate the fertility status of kinnow orchards at Rawatsar and Fatehgarh soil series Hanumangarh district in irrigated area arid Rajasthan. All soils were found saline nature, EC2 all orchard samples normal. calcium carbonate content showed increasing trend with depth, low organic carbon available N, medium P2 O5, high K2O content, majority Fe, Mn sufficient...

Robotics and intelligent sensing systems can provide useful information to improve yield and quality in specialty crop production. A key requirement for treecrop applications is the ability to associate sensed data to the individual trees in an orchard. A mobile ground robot with a scanning lidar (laser range sensor) is used to build a three dimensional (3D) model of an orchard and algorithms a...
