The possibility of using paper mill lime sludge as a soil amendment in an acid soil was investigated. Sludge used contained 58.4% calcium carbonates plus a small amount of heavy metals. A pot experiment was conducted with an acid soil and Sorghum vulgaris variety speed seed as test plant. Treatments with three replicates consisted of 0, 0.5 and 1, 2 and 4% paper mill lime sludge (L0, L0.5, L1, ...

2.5 pounds of lime to 100 gallons of water) or zinc oxide (2 pounds to 100 gallons) may be used. For severe cases in Florida, twice the indicated dosage of zinc sulfate and lime is recommended. Sprays should be applied soon after new growth appears. Iron deficiency occasionally occurs in California, primarily in trees on calcareous soils. It is characterized by yellowing of the major portion of...

Agricultural liming materials are used to correct soil acidity and to improve plant growth and microbial functionality. A relatively low-grade agricultural lime was found to contain up to 125 mg kg(-1) arsenic (As), which is above any fertilizing materials code threshold. The color of the milled material is brown due to ample oxide dendrites. Microprobe elemental maps confirmed that these acces...

A 3, NPK lime factorial experiment is used as a means of testing both soil and leaf norms for sugarcane obtained by the Diagnosis and Recommendation Integrated System (DRIS) developed by Beaufils. ,Soil and leaf samples were taken from the experiment when the cane was 3, 6, 12 and 18 months old respectively and analysed for a number of essential plant nutrients. The results show that these norm...

The objective of this research was to identify the vegetation-soil relationships in Nodushan arid rangelands of Yazd. 5 sites were selected for measuring the cover of plant species and soil attributes. Soil samples were taken in 0-10 and 10-80 cm layers. The species studied were Salsola tomentosa, Salsola arbuscula, Peganum harmala, Zygophylum eurypterum and Eurotia ceratoides. Canonical corres...

This study investigates the combined efficacy of waste-tire-derived aggregate (TDA) materials and hydrated lime on compactability, compressive strength swelling potential a highly expansive soil from South Australia. A total 21 mix-designs, covering comprehensive range soil–TDA–lime combinations, were examined through standard Proctor compaction, unconfined (UCS) oedometer swell tests. The mobi...

Two field experiments (Spring, 1974 and 1975) were conducted on Myakka fine sand to determine the effect of lime and nitrogen source on the development of Fusarium wilt of cucumber and watermelon. The same site, with the same experimental design, was used for each experiment. In both experiments, gross yields were increased and wilt development decreased by raising the soil pH with hydrated lim...
