Spent coffee grounds improve the nutritional value in elements of lettuce (Lactuca sativa L.) and are an ecological alternative to inorganic fertilizers
A Cervera-Mata, M Navarro-Alarcón, G Delgado… - Food chemistry, 2019 - Elsevier
The element concentration in lettuces grouped in 5 categories (baby variety, cultivated in
agricultural soils with low or high percentages of spent coffee grounds-SCG, without SCG
and with NPK) were measured. Lettuces cultivated in agricultural soils amended with SCG
had significantly higher levels of several essential (V, Fe, Co, V, and probably Mn and Zn)
and toxic elements (Al and probably As), without reaching their toxicological limits.
Additionally, blocking of N uptake and therefore plant biomass, and probably Cd absorption …

Spent coffee grounds improve the nutritional value in minerals of lettuce (Lactuca sativa L.) and are an ecological alternative to inorganic fertilizers
JÁ Rufián Henares, S Pastoriza de la Cueva - 2019 - digibug.ugr.es
The concentrations of several essential and toxic mineral elements of five groups of lettuces
(non-cultivated, cultivated with low or high percentages of spent coffee grounds-SCG,
without SCG and with NPK) were compared. The influence of adding increasing amounts of
SCG in an in vitro assay with a crop soil from Vega of Granada (Spain) was studied. Lettuces
with SCG had a higher level of most essential elements (Fe, Co, V, Mn and Zn) as well as
some toxic elements (As, Pb and Al), without exceeding the limits established for these …
