“…For sieving, we used the wet-sieving methodology (Angers et al 2006 Soil enzymatic activity was identified after faba bean harvest (3 October 2016, 2 October 2017, 6 September 2018) before primary soil tillage (in 0-15 cm layer). The activity of the soil enzyme urease was determined by the methods of Hofmann and Schmidt (1953), saccharase by Hofmann and Seegerer (1950) and Chunderova (1973).…”

Decreased tillage intensity can contribute to a reduced agro-technological footprint and stabilise the negative impact of climate change, especially in leguminous crop cultivation. For this reason, a long-term (since 1988) stationary field experiment has been performed on silty loam Planosol (in Lithuania). The main objective of this study was to establish the influence of sustainable tillage and no-tillage systems on soil aggregate stability to water, penetration resistance, enzymatic activity, abundance of earthworm and faba bean grain yield. Five different tillage systems were investigated: conventional deep and shallow mouldboard ploughing, deep chiselling, shallow disking and no-tillage. No-tillage in faba bean cultivation significantly increased soil structural stability by 40–97%, saccharase content by 0.7–2.0 times, urease activity by 3–4 times, the average quantity of earthworm by 55% and the biomass by 3.6 times. The impact of other ploughless tillage systems on soil properties was positive but not as significant. Faba bean grain yield was more influenced by growing seasons than by different tillage methods.

“…The samples were air-dried, crushed in a porcelain mortar and sieved with a 2 mm sieve. The soil samples were analysed for: available phosphorus (P 2 O 5 ) concentration mg kg -1 by the CAL method using a spectrophotometer Beckman DU-40; available potassium (K 2 O) concentration mg kg -1 by the CAL method using a flame photometer Corning PC-410; ammonia nitrogen and nitrogen (sum of nitrate and nitrite nitrogen) concentrations mg kg -1 by a flow injection analysis (FIA) spectrometric method using inductively coupled plasma mass spectrometry (ICP-MS, Thermo Finnigan MAT, Germany); mineral nitrogen concentration mg kg -1 was calculated as a sum of nitrogen (nitrate and nitrite) and ammonia nitrogen; activity of soil enzymesurease was measured after Hofmann and Schmidt (1953) methods and saccharaze -after Hofmann and Seegerer (1950) methods, 4 times -before the spray application and 7 days, 14 days and 126 days after the spray application with BD preparation 500.…”

The aim of this research, which was undertaken in three years (2013-2015), was to evaluate the effect of biodynamic (BD) preparations 500 and 501 on soil biological and agrochemical properties and potato tuber quality. The soil samples were analyzed for: available phosphorus, available potassium, ammonia nitrogen, nitrogen (sum of nitrate and nitrite nitrogen) and mineral nitrogen. The potato samples were analyzed for: total polyphenols content, total anthocyanin’s content and antiradical activity. The research revealed that significantly the highest concentrations of available phosphorus, available potassium, nitrogen and mineral nitrogen in the soil throughout the growing season were identified on the 14th day after soil application of BD preparation 500 (before potato planting). As well as, soil spray application of BD preparation 500 resulted in higher enzyme activity (urease and saccharase). When the BD preparation 501 was applied, the content of total phenolic compounds in the tubers of cultivars Blue Congo and Red Emmalie was significantly higher, 20.1% and 5.4%, respectively; the content of anthocyanins were significantly higher in the tubers of three tested cultivars. However, the application of this preparation did not have any effect on the content of total phenolic compounds and on the antioxidant activity of Vitelotte tubers. The use of both preparations (500+501) had significant effects only on anthocyanins accumulation in the tubers of Blue Congo and Vitelotte. The application of preparation 500 significantly decreased the content of anthocyanins in the tubers of cvs. Red Emmalie and Vitelotte.
