“…Soil salinity causes soil organic matter (OM) flocculation, which leads to OM loss due to wind erosion and leaching (Artiola and Walworth, 2009;Kida et al, 2017;Martinez et al, 2002;Wong et al, 2010). Salinity not only accelerates the decrease of soil OM but also increases the accumulation of harmful trace elements in plants (Ondrasek et al, 2012), inhibits the microbial activity in soils (Setia et al, 2014), and delays the decomposition of soil organic residues (Peinemann et al, 2005).…”

ADDITIONAL INDEX WORDS. organic matter recycled water, salt, saline, topdressing, turfgrass SUMMARY. Increased use of recycled water along with inherent soil salinity problems on golf courses make salinity an important issue for golf course management. The objective of this study was to investigate if using humus on golf fairways by topdressing or spraying can alleviate soil salinity problems and improve turf quality. The study was conducted from 2015 to 2017 at Aurora, CO, and Medora, ND. Treatments included an untreated control, topdressing (sand, sand D peat), and spraying of humic acid. Our results showed that the application of humus increased the soil microbial biomass and improved turf quality on fairways either with a soil salinity problem or irrigated with recycled water. The effects on turfgrass health and turf quality were dependent on the rates of humus applied. Humic acid at 3 gal/acre was equivalent to topdressing sand D peat (80/20 v/v) and consistently showed improved turf quality over the untreated control. Soil properties also were affected by the application of humus. Soil pH, electrical conductivity (EC), bulk density, water infiltration, and microbial biomass may have had an indirect contribution to turf quality.

“…The first is that these soils and rocks contain large amounts of calcium in primary calcareous minerals. The second is that, among other cations, Ca ++ is easily absorbed by clay minerals, especially humic substances (Martínez et al 2007). The high content of Ca ++ in the lower horizons of both soils was mostly due to the calcareous rock material, while the sharp decrease in Ca ++ in the B1 and lower horizons can be explained by the drop in the humus content.…”

The fertile arable lands in the dry steppe zone of the Ural piedmont, which were intensively used for cereal production for 30 years of the last century, have been withdrawn from cultivation and abandoned for the last 20 years. The Republic of Kazakhstan's new strategy to restore the productivity of natural pasture presents a challenge to scientists when it comes to restoring the natural soil properties to the natural pastoral conditions of the dark chestnut soils studied (Haplic Kastanozems). This chapter presents the results of a project devoted to investigating the changes in the soil's physical and chemical morphology due to the past cultivation history of Haplic Kastanozem soils that have been in a fallow state for the last 19 years. Some changes in the soils' morphological characteristics were caused by the changes in the soils' physical properties due to their past long-term cultivation. The changes observed in the soils' agrochemical characteristics were due to the changes in the soils' physical properties and to the past fertilization history. A minor increase in soil salinity was observed due to the greater accumulation of soluble salts in the arable layer of fallow soil compared to its virgin Haplic Kastanozem analogue. The changes and transitions in the vegetation composition need to be investigated further, and techniques should be developed for the accelerated restoration of fallow soils in dry-steppes of Western Kazakhstan.
