Field trials were conducted at the Research and Study Farm “Pēterlauki” (56°53' N, 23°71' E) of the Latvia University of Life Sciences and Technologies in 2022/2023. Soil characteristics: sod calcareous soil with following agrochemical parameters: pH KCL 6.7; organic matter content – 26 g kgE−1; phosphorus content – 60 mg kgE−1 P2O5; and potassium content – 144 mg kgE−1 K2O. Winter wheat (Triticum aestivum) sowings were established using different variants of a fertilizer mix with cattle manure digestate (from “Ziedi JP”, Ltd) (D) and wood ash (P) (from “Gren Jelgava”, Ltd) in different ratios. The norms of the innovative mixed fertilizer from cattle manure digestate and wood ash were 5, 10, and 20 t haE−1. Winter wheat plots fertilized only with digestate were used as control. Variants in the two-factor trial were randomized in triplicate. During the experiment, the influence of the researched factors on winter wheat grain yield, the content of starch and protein in grains, grain volume weight (kg hLE−1), and the mass of 1000 grains was determined. It was established that the average winter wheat grain yield in the control variant (D:P=1:0) was 5.29 t haE−1, which is significantly (p<0.05) lower than the average yield in the variants using fertilizers of digestate and wood ash mixtures (6.05 t haE−1).
