Abstract
Analysis of soil physico-chemical properties of guava orchard in multi zones of district Larkana, Sindh, Pakistan
Highlights
S (16 tress) of each orchard at three soil depths (0-15, 15-30 and 30-45 cm).The soil samples were analyzed for some physical and chemical properties of the soil
In case of organic matter, results of this study revealed that all soil samples were found poor (
The collected soil samples were analyzed for particle size distribution by Hydrometer method, EC and pH were determined by digital EC and pH meter, calcium carbonate, and organic matter was determined by Walkley and Black method, soluble Na+, K+ were analyzed by ammonium acetate method, extractable Ca+ and Mg+ were analyzed by ammonium acetate and soluble Cl- was determined by Mohar’s titration
Summary
Orchard soils under semiarid/arid productivity [2]. Restoration of the soils are subtropical regions have low organic carbon important if tree crops are planted from view content and inherent low soil fertility status point of orchard sustainability and [1]. Among fruits guava has importance in Pakistan fruit industry and it is ranked as 4th place on the basis of area (62.5 thousand ha) and production (555 thousand tons) [5]. Sindh contributes 9.8 hectares of area under guava with a total production of 75.4 tons [6]. The taking away of nutrients from guava orchards happens because of the harvested fruit, as was stated earlier, and by pruning the trees. Materials and methods This study was conducted to investigate soil physico-chemical properties of guava orchards soil of district Larkana, Sindh. The collected soil samples were analyzed for particle size distribution by Hydrometer method, EC and pH were determined by digital EC and pH meter, calcium carbonate, and organic matter was determined by Walkley and Black method, soluble Na+, K+ were analyzed by ammonium acetate method, extractable Ca+ and Mg+ were analyzed by ammonium acetate and soluble Cl- was determined by Mohar’s titration
