“…Diatomites are rocks formed by the transformation of diatom shells. These materials stand out for their interesting properties and many applications [1,3,8,9]. In order to improve the properties of diatomite, expensive chemical and physical functionalization methods have been developed.…”

Diatomite has recently been the subject of intensive scientific research aimed at its extensive use in industry, breeding and agriculture. The only active diatomite mine is in Jawornik Ruski, in the Podkarpacie region of Poland. Chemical pollution in the environment, including that from heavy metals, poses a threat to living organisms. Reducing the mobility of heavy metals in the environment through the use of diatomite (DT) has recently gained much interest. More effective immobilisation of heavy metals in the environment with DT, mainly through the modification of its physical and chemical properties by various methods, should be applied. The aim of this research was to develop a simple and inexpensive material showing more favourable chemical and physical properties compared with unenriched DT in terms of metal immobilisation. Diatomite (DT), after calcination, was used in the study, considering three grain fractions, i.e., 0–1 mm (DT1); 0–0.5 mm (DT2) and 5–100 µm (DT3). Biochar (BC), dolomite (DL) and bentonite (BN) were used as additives. The proportion of DTs in the mixtures amounted to 75%, and of the additive, 25%. The use of unenriched DTs after calcination poses the risk of releasing heavy metals into the environment. Enrichment of the DTs with BC and DL resulted in a reduction or absence of Cd, Zn, Pb and Ni in aqueous extracts. It was found that for the specific surface area values obtained, the additive used for the DTs was of crucial importance. The reduction in DT toxicity has been proven under the influence of various additives. The mixtures of the DTs with DL and BN had the least toxicity. The obtained results have economic importance, as the production of the best quality sorbents from locally available raw materials reduces transport costs and thus the environmental impact. In addition, the production of highly efficient sorbents reduces the consumption of critical raw materials. It is estimated that the savings from producing sorbents with the parameters described in the article can be significant in comparison with popular competitive materials of other origins.

“…The decomposition rate of peats is only about 5-10% of the total biomass of peats. Accumulating peats occur if the decomposition rate is lower than the rate of organic matter accumulation (Kaleta et al, 2019;Mulyono et al, 2019). Consistent accumulation of organic matter (partially decomposed) continues to support the formation of peats.…”

The research aimed at comparing the chemical properties of peats under different land uses in peats dome of the catchment area of the Sibumbung River and the Komering River in Pedamaran Sub-Districts, OKI South Sumatra, Indonesia. The research was conducted in January 2019 and used a Randomized Complete Block Design with two blocks and five natural treatments namely swamp grass, bush swamp, peat forest, oil palm, and intercropping between oil palm and pineapple. Most of the chemical properties of peats at the depth of 30-50 cm showed no changes due to the effects of land uses and drainage; however, there were significant differences with the peat depth of 5-15 cm. Decreasing organic C, exchangeable Al, Al saturation and soluble Fe on the cultivated peats were significantly different compared with the uncultivated peats. An increase in the available P, K, pH, CEC and base saturation on the cultivated peats were found and differed significantly on test level 5% compared with the uncultivated peats due to the application of ameliorant materials. The total N and C/N values were not significantly different. Most of the chemical properties of peats were decreased by the depth of peats. Soil ameliorant materials would change the buffering system of the peats to neutralize soil acidity and the pH increase.

“…The development of sugarcane plantations demands concept application of precise agriculture (precise farming), namely precision of location (Martins et al, 2018; Baranowska et al, 2019), dose, time, data and information as well as technology (Carvalho et al, 2018;Wildayana et al, 2016). Such precise agriculture will lead to the management system based on technology and needed information, which is capable of identifying, analyzing, and site-specific managing of temporal and spatial soil variability, thus the optimal sugarcane productivity can be achieved, which is beneficial, sustainable (Wildayana and Armanto, 2018; Rybak et al, 2019;Kaleta et al, 2019) and does not pollute the environment due to input and agricultural machinery (Li, 2018;Guzeeva, 2019). This concept will be able to identify the level of soil suitability to sugarcane, status of soil fertility, and other soil and water quality parameters (rooting condition, soil acidity, oxygen and water availability, retention and buffering capability as well as topography).…”

Uniforming sugarcane management without any knowledge of soil variability could result in some parts of a sugarcane field receiving insufficient inputs, while other parts receive an excessive input. The research aimed at assessing the soil variability and sugarcane biomass along Ultisol toposequences in Central Lampung, Indonesia. Two sugarcane catenas and one forest catena were fully described in the fields. Soil horizons are represented by Ap/Ah/M, E, B, Cc and Cg with dominant clay translocation. The gleying symptom was found only in the lower slope to depression. The concretion depths can be used as an erosion indicator if the soil parent material is well characterized. Soil P has a maximum value of Ap horizon and decreases with the depth and no effect of internal erosion in the form of soil P accumulation in subsoils can be observed, except for the colluviated horizon. Kaolinite clay is dominantly found to buffer the changes in pH, except Ap horizon of sugarcane. The organic C depends on the pedogenesis and catena form. Al saturation indicates that the dominant soil weathering is intensive. Al saturation in the Ap horizon (Catena G1; G2) was reduced from 80% to 20-40% caused by liming and fertilization. The catena position was the main factor causing the increasing soil variability, which was responsible for the variability of sugarcane biomass. The sugarcane biomass increased with decreasing slopes. The highest biomass was found in the depression (105 tones/ha) if the sedimentation process is characterized by the formation horizon M and accompanied by the nutrient accumulation from the hilltops.
