Potassium and Phosphorus Releasing Capacity of Latosols under Tea Cultivation in South India

study of potassium fixation capacity in some under-cultivation sugarcane soils in khuzestan

abstract this study was conducted to investigate, under incubation conditions (fc moisture and temperature of 30o c), the effect of the potassium concentration and the cultivation background on the k- fixation in khuzestan’s sugarcane under-cultivation soils. for this reason, 70 complex soil samples in 35 pairs each coupled out of two different depths (0-30 and 30-60 cm), chosen from the under-...

the effect of oxytetracycline on serum calcium, phosphorus and magnesium in cattle

نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...

Impact of Continuous Training of Occupied Manpower in Tea Cultivation and Industry on Quality of Produced Tea

Due to lack of using pesticides in production of green leaf, Iran’s produced tea is considered as of the purest and healthiest teas in the world [1]. Although, by passing one century from commencement of tea cultivation and production in Iran, tea cultivation surfaces has been developed and numbers of tea making factories has been increased, no progress has been made in improvement of quality o...

Cultivation of Ipecacuanha in India

Fractions, uptake and fixation capacity of phosphorus and potassium in three contrasting soil orders

A controlled greenhouse experiment was conducted to study the fraction, uptake and fixation of phosphorus (P) and potassium (K) in three soils with contrasting characteristics. The experiment was carried out in two phases, viz., sorghum-Sudangrass depletion and test crop experiment with maize with three levels of fertility status (depleted, original and fertilized with 40 mg kg-1 P and K) and t...
