Exchangeable lead (Pb) in lowland paddy soils of Sri Lanka as affected by the differences in agro‐climatic zones, soil orders, and water sources

PLANTS, PEOPLE, PLANET, EarlyView.
Lead (Pb) accumulation in the human body poses serious health risks. As rice is the staple food in Sri Lanka, with a high per capita intake (114 kg), there is a significant risk of Pb transfer through rice consumption. This study evaluated exchangeable Pb concentrations in soils and produced Pb distribution maps.

Positive Polynomials on Riesz Spaces

, 2016
We prove some properties of positive polynomial mappings between Riesz spaces, using finite difference calculus. We establish the polynomial analogue of the classical result that positive, additive mappings are linear.

Steaming soil is effective in eliminating invasive alien plants (IAPs) – part I: effect of exposure method

Pest Management Science, Volume 81, Issue 4, Page 2032-2039, April 2025.
As regulations on chemical pesticides become more stringent, it is likely that there will be interest in water steam as an alternative approach for soil disinfestation. This study investigated the feasibility of utilizing a soil steaming device for thermal control of selected invasive alien plants and showed a promising mortality rate for their ...

NPK Fertilization of Cilantro and Dill

HortScience, 1995
Two experiments, one each with cilantro and dill, were conducted during 1994 to determine optimum rates of N, P, and K fertilizers. In these experiments, `C1410' cilantro and `Bouquet' dill were direct seeded in three-row plots with 0.3-m spacing between rows. A seeding rate of ≈40 seeds per meter of row length was used.
