Spatial variability of thermal properties in relation to the application of selected soil-improving cropping systems (SICS) on sandy soil
. The study aimed to determine the effect of randomly applied soil-improving cropping systems on the variability of soil thermal conductivity, heat capacity, and thermal diffusivity over the course of a 3-year (2016-2018) study. The field experiment included the control and the following soil-improving cropping systems: liming, leguminous catch crops for green manure, farm yard manure, and liming+leguminous catch crops+farmyard manure together with spring oats (2017) and spring wheat (2018). The parameters such as bulk density, water content, and values of soil thermal conductivity, heat capacity, and thermal diffusivity have been determined. The thermal properties were measured at the current water content in situ and in water-saturated and dry soil states in the laboratory. The thermal properties in the wet year of 2017 increased in the subareas with a predominance of leguminous catch crops for green manure, farmyard manure, and liming+leguminous catch crops+farmyard manure, whereas the soil-improving cropping systems effect was not consistent after stubble tilling in the dry year of 2018. Cross-semivariograms which used the sand content as an auxiliary variable and cokriging produced a better prediction than the semivariograms and kriging. The fractal analysis indicated that the number of subareas differing in thermal properties was mainly modified by water content and bulk density. The spatial spread of the soil thermal properties during the water-saturated and dry states increased in subareas with a higher bulk density.
期刊介绍:
The journal is focused on the soil-plant-atmosphere system. The journal publishes original research and review papers on any subject regarding soil, plant and atmosphere and the interface in between. Manuscripts on postharvest processing and quality of crops are also welcomed.
Particularly the journal is focused on the following areas:
implications of agricultural land use, soil management and climate change on production of biomass and renewable energy, soil structure, cycling of carbon, water, heat and nutrients, biota, greenhouse gases and environment,
soil-plant-atmosphere continuum and ways of its regulation to increase efficiency of water, energy and chemicals in agriculture,
postharvest management and processing of agricultural and horticultural products in relation to food quality and safety,
mathematical modeling of physical processes affecting environment quality, plant production and postharvest processing,
advances in sensors and communication devices to measure and collect information about physical conditions in agricultural and natural environments.
Papers accepted in the International Agrophysics should reveal substantial novelty and include thoughtful physical, biological and chemical interpretation and accurate description of the methods used.
All manuscripts are initially checked on topic suitability and linguistic quality.
