The experiments were done on a productive clay loam Gleyic Cambisol used for agricultural production and were designed to estimate the effects of various catch crops—red clover (Trifolium pratense L.) and white clover (Trifolium repens L.) mixture with Italian ryegrass (Lolium multiflorum

The most SOM was accumulated in pre-mainland section of floodplain meadows of Nevėžis; this quantity exceeds more than 5 times SOM content in agrarian land grown with swards, and also was higher than SOM content of wood pasture. However, amount of SOM in surface soil layer (0–10 cm) of pre-mainland section was equal to 143.2 g kg -1 soil, in 10–20 cm layer – 81.4 g kg -1 soil, and in 20–30 cm layer – 30.9 g kg -1 soil. The most unfavorable status of SOM was determined in the soil of riverside section of floodplain of the Nevėžis River. It characterizes low concentrations of SOM – 14.6, 7.0, and 7.3 g kg -1 soil in the 0–10, 10–20 and 20–30 cm layers, respectively, and relative share of MHS accounted for as much as 47.8–57.9% of soil organic carbon.

The aim of the study was to compare the soil organic carbon (SOC) as well as carbon of mobile humic acids (MHA) contents in the differently used agricultural soils. The data of SOC and MHA investigated in four different field experiments are discussed in this article. In the Experiment 1 the study investigated two soil tillage systems: conventional and sustainable (factor A) and crop rotations with different structure of winter crops (0−100%) (factor B) on a Endocalcari-Endohypogleyic Cambisol at the Joniskelis Research Station of LIA. The field Experiment 2 compared the influence of long-term legume swards on SOC and MHA in an Epicalcari-Endohypogleic Cambisol. In the Experiment 3 the treat-ments of factor A involved 7 different swards and the treatments of factor B of this experiment involved frequent and less frequent grazing. Five past...

The book comprises 14 chapters. In the chapters 1 to 5 the importance of long-term studies is discussed, Lithuanian soils, their properties and research development, agroclimatic conditions are described, the review of many-year experiments as well as the research objectives and conditions are presented.
