Nitrogenous Fertilizer Application Rates and Plucking Intervals on Tea [Camellia sinensis (L.)] in Eastern Africa: Changes in Soil Calcium, Magnesium and Manganese Levels

Robert O. Ombori, P. Okinda Owuor, Bowa O. Kwach, David M. Kamau, Wilson Dufitumukiza & Solomon W. Msomba · Asian Soil Research Journal · 2025

Tea production requires high rainfall areas that cause nutrients depletion through surface run-off, leaching, and removal with crop. This makes application of fertilisers mandatory to replenish the nutrients. However, such applications could cause soil nutrients imbalance. Harves...

Nitrogenous Fertilizer Application Rates and Plucking Intervals on Tea (Camellia sinensis (L.) in Eastern Africa: Effects on Soil Nitrogen, Phosphorous, and Potassium

Robert O. Ombori, P. Okinda Owuor, Bowa O. Kwach, David M. Kamau, Wilson Dufitumukiza & Solomon W. Msomba · Asian Soil Research Journal · 2025

Eastern Africa tea grows in high rainfall areas where nutrients depletion through leaching, surface run-off in addition to removal with crop can be high. Nutrients replenishment through fertilizer applications is therefore necessary. The recommended fertilizer application rates a...
