Response of spring barley to PRP SOL application as a complex of mineral inducer process (MIP)

Abstract

Summary. The aim of the application of a PRP SOL complex of MIP bioactive compounds is to improve the soil characteristics by unblocking the potential of the nutrients in the soil and making them available to plants. This fertilizer is used for soil fertilization rather than crop nutrition. The research focused on evaluation of the yield of spring barley after the application of the PRP SOL technology in the fields of the Research and Education Center Gorzyń, at the Experimental Station in Złotniki, in 2007 to 2011. The purpose of the research was to compare the effects of spring barley fertilization technology by applying a complex of MIP bioactive compounds in the form of a PRP SOL fertilizer with the standard technology applying phospho-potassium fertilization. The five years of the research led to the conclusion that the traditional fertilization of spring barley plantations with phosphorus and potassium can be replaced with the technology applying the MIP complex without grain yield losses. However, the yield was not stable between years. In one of the five research years (2007) there was a significant increase (by 3.7 dt•ha -1 ), and in another (2010) a significant decrease (by 3.2 dt•ha -1 ) as a result of fertilizer use. The PRP SOL fertilizer may be particularly useful for malting barley due to the favourable increase in the share of lush grain fractions (larger than 2.5 mm) and simultaneous decrease in the share of smaller grains and due to the fact that the weight of 1 hl tends to decrease whereas the thousand grain weight tends to increase.

Effect of Soil Conditioning on the Moisture Content and the Salt Profile of the Soil Under Irrigation with Saline Water

“…In harmony with the results of Borowiak et al (2016), Sulewska et al (2016) and Wojciechowski (2015), improved soil status could be achieved by means of the application of Neosol. In close correlation with the water regime of the soil (based on the improved soil structure), slight mitigation of the harmful effect of secondary salinization can be figured out, but this effect is highly dependent of the total annual salt load gets into the soil through irrigation.…”

“…Though our experiment is very complex, in this paper our results gained by studying the effect of soil conditioning are described only. The aim of the application of the Neosol soil conditioner is to improve the soil characteristics by unblocking the nutrients in the soil and making them available to plants (Sulewska et al 2016). Soil, where Neosol was applied, showed a higher moisture level, especially in the 0.25 -0.3 m soil depth.…”

Investigation of the possibility of green bean production under unfavourable agro-ecological conditions in lysimeters

“…According to the producer, the microbiological activity of the soil can be boosted by Neosol (distributed in pellet form) and thus also its fertility [10]. Through the application of Neosol, the soil characteristics can be improved by unblocking the nutrients in the soil [5].…”

Physical properties of a soil under a pig slurry application and organic matter activators

“…The positive effect of PRP SOL on the soil enzymatic activity was confirmed by the study of Niewiadomska et al (2018). Although this product cannot be considered a conventional fertiliser, PRP SOL can replace the traditional fertilisation of spring barley without a negative effect on the grain yield (Sulewska et al 2016). There is a great lack of scientific studies regarding the activators, although a few do exist.…”
