The mineral composition of cereal crops, the technological value of grain and flour, as well as bread quality are affected by the genotype, environment, and agronomic management practices. The aim of the research has been to investigate the effect of the environment and agronomic factors on the mineral composition and baking value of winter wheat grain. Opal cultivar grain of the genetically determined prime-quality wheat was obtained in a two-year field experiment (varied soil and weather). The agronomic management practices included tillage (conventional moldboard-plow, reduced ploughless, and strip-till) and nitrogen fertilisation rate (100 kg·N·ha−1, 200 kg·N·ha−1). In the grain samples, the content of macronutrients was assayed: P, K, Mg, Ca, and Na, total protein, and wet gluten as well as sedimentation value. The colour and the water absorption of flour and its content of protein and ash were determined. Laboratory baking was performed. It was found that the content of protein and gluten in grain, sedimentation value, bread volume, and weight changed depending on the environmental conditions and research years. Tillage and nitrogen rate, despite an effect on the properties of grain and flour, did not differentiate, however, the bread quality. The environmental conditions and agronomic management practices did not have a significant effect on the content of mineral nutrients in grain, except for calcium. The biofortification with mineral nutrients in prime-quality winter wheat cultivar grain by selecting the environmental and agronomic conditions seems more difficult than increasing the content of organic compounds and enhancement of flour and bread parameters.

For 10 years (1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008) there was investigated the effect of liming on soil pH KCl and on organic carbon, available forms of macroelements and DTPA-extracted forms of some metals in 6 different fertilization objects in a longterm experiment set up in 1948: without fertilization (0), straw + NPK (STR NPK), NPK, farmyard manure (FYM), FYM NPK, FYM NPKMgCa. As a result of the application of 12.0 t/ha of lime (4.3 t Ca/ha), an increase was found not only in soil pH value but also in organic carbon, plant available phosphorus, zinc and copper contents and a decrease in manganese content. Despite significant changes in the soil properties, they still varied across the longterm fertilization objects.

The non-inversion tillage systems, including strip-till (ST), are the key element of conservation agriculture (CA). The aim of the 2012–2018 study has been to demonstrate the application of strip-till one-pass technology (ST-OP) on the farms of Central and Eastern Europe based on the use of Mzuri Pro-Til machines. There has also been an evaluation of the effect of that technology on the soil properties and the effects of crops growing. The scientific observations and field experiments were made, e.g., in Poland, Ukraine, Lithuania, the Czech Republic, Slovakia, the Eastern states of Germany, Belarus, Serbia, and Romania. ST-OP case study with the use of Mzuri Pro-Til machine can be applied for growing all the basic crops. Tillage with a simultaneous basic fertilization application and seeding made regularly for a few years in given field leads to favorable changes in the soil properties. As compared with the soil under conventional plough tillage (CT), the soil moisture, especially in the periods of rainfall deficit, the content of organic carbon and its fraction, the count of microorganisms and earthworms, as well as the enzymatic activity, are higher. This technology saves over 20–30 L ha−1 of fuel, respectively, compared to reduced tillage (RT) and CT. Plant emergence is uniform, dense canopies and crop yields—not lower and even higher than for tillage and seeding commonly applied in Central and Eastern Europe. ST-OP can be thus an important element of field plant production as part of CA and sustainable development.
