A 2-year field trial determined the influence of applying spent mushroom substrate (SMS) on soil physical properties and the growth of 4 consecutive vegetable crops (sweetcorn, cabbage, potato, cabbage). Treatments comprised 0, 20, 40, and 80 t/ha of moist SMS, both with and without inorganic fertiliser, applied to each crop, giving a range of SMS rates up to 320 t/ha. SMS improved the environment for plant root growth by decreasing soil bulk density (by 0· 05-0·25 g/cm 3 at 100 mm depth), increasing aggregate stability (by 13-16%), reducing clod and surface crust formation (by 16-31 and 18-94%, respectively), increasing the infiltration rate (by 130-207 mm/h), increasing the water content of the soil (by 0-7% w/w), and reducing diurnal temperature changes. Some of these changes were not evident until repeated applications of 80 t/ha SMS had been made. Soil physical properties were related to crop yield, and soil physical properties’ principal components were related to crop principal components using regression analysis (r2 of 0·20-0·60 and 0·16-0·54, respectively). The soil physical properties that had the most influence on plant growth were specific to each crop and included bulk density, water content, surface crust cover, infiltration rate, and aggregate size distribution. Soil physical properties had a large influence on the potato yield irrespective of fertiliser use and on both cabbage crop yields when fertiliser was not used, but not on the sweetcorn yield (the first crop to be grown). The effect of changing soil physical properties on plant growth was most apparent when fertiliser was not used. This was because the improved physical properties increased plant yield (at least in part) because of increased plant nutrient uptake.

A research about utilization of cylindrica biomass as an OM source was conducted to improve physical properties and to reduce soil erosion of degraded land and. The area of degraded land is quite large and the cylindrical biomass as a soil ameliorant is enough amount to use. The research was aimed to evaluate the effect of cylindrical biomass to improve properties and to reduce erosion of degraded Ultisol. Cylindrica biomass was treated as mulch as well as compost, sprayed with Round up, and removed from the land as farmers used to do. The field research was designed in Randomized Block Design (RBD). The result showed that cylindrical biomass was able to improve soil physical properties (BD, TP, infiltration rate) and to reduce erosion lower than the tolerated one.

This study investigated the influence of the environmental characteristics and soil properties on the soil infiltration rate in urban permeable area. The experiments were conducted at nine sampling points located in the urban perimeter of Campo Grande, capital city of Mato Grosso do Sul State, in the Brazilian Midwest. The infiltration rates were determined using a portable integrated rainfall and overland flow simulator. Each experiment was repeated three times, and a total of twenty-seven plots were collected. At the same time, environmental characteristics and soil physical properties, that may affect infiltration rate, were also evaluated. The relationship between the infiltration rate, the environmental plot characteristics and the soil physical properties was verified using a linear correlation matrix.

The result of long time farming and poor soil management and conservation practices at Niger state college of Agriculture Mokwa Commercial farm which is the study area has led to serious soil degradation like nutrient depletion and soil erosion. There is the need for local content research and innovation to ameliorate the problem. This research work described the effect of organic manure and inorganic fertilizer (poultry manure, Cow dung and NPK fertilizer) on some soil physical properties i.e. the infiltration, porosity, bulk density and erodibility on a sandy loam soil of Mokwa North Central Nigeria. Four treatments of poultry, cow dung manure, NPK 15:15:15 fertilizer and non – application were applied in RCBD with 25t/ha of poultry manure and cow dung while NPK 15:15:15 was 150kg/ha and non- application as control replicated three times. Soil physical properties were measured and analyses were done to ascertain the soil aggregates. Ring infiltrometers were constructed and used to test the infiltration rate of the soil at each plot before soil treatments. Measurements were taken at time intervals for all the plots. The plots were then treated with manure and NPK and left for two weeks to decompose, after which infiltration measurements were taken again. Minitab 17 and Excel were used for the analysis. The cow Dung manure shows highest infiltration rate as compared to other treatments. The experiment shows that Cow Dung and poultry manure can be used to correct infiltration and soil physical anomalies especially when soil is compacted or clayey.

This study was conducted to compare the long-term (20 yr) effects of conventional tillage, minimum tillage and no-till on various soil-water related properties within the tilled layer (0–30 and 30–60 mm) and immediately below the tilled layer (90–120 mm) under a spring cereal-summerfallow rotation cropping system. Parameters measured included saturated hydraulic conductivity, saturation percentage, plant-available water-holding capacity, large pore porosity, bulk density, and infiltration rate of the soil. Tillage treatment effects on these soil properties in each of the four sampling periods were not significantly different. The confidence interval test showed some temporal changes in these soil physical properties, of which hydraulic conductivity was the most affected. In the summerfallow field, regardless of the previous cereal crops, the steady infiltration rate was significantly lower in the soil under conventional tillage than with that under no-till. The results indicate that the surface soil structure was most stable under no-till. In the fresh stubble field, the type of cereal crop had an effect on the infiltration rate of the soil. The mean infiltration rate was higher in the summerfallow field than in the fresh stubble field and also was higher in the fresh barley stubble than in the fresh wheat stubble. Except for infiltration rates, there is no significant advantage of one tillage method over the other with respect to the soil physical properties measured in this Brown Chernozemic clay loam soil. Key words: No-till, minimum tillage, hydraulic conductivity, bulk density, infiltration

Soil infiltration capacity is one of the key factors in the soil protection against unfavourable effects of water erosion. The purpose of its measuring was to compare and evaluate the changes of the soil physical properties and of water infiltration into soil caused by different intensity of soil cultivation at two individual sites. The ploughing (PL), shallow tillage (ST), and direct drilling (NT) effects on the soil physical properties, water infiltration into soil, and soil surface coverage with the crop residua under the soil condition loamy Haplic Luvisol, with long-term growing of maize (Zea mays L.) - Agroservis, 1<sup>st</sup> Agricultural, a.s., Vi&scaron;ňov&eacute; - and clay soil of Calcic Chernozem (Cooperative farm Klap&yacute;), were compared. Soil bulk density values in the variant with ploughing showed in the depth up to 0.20 m considerably lower values as compared with the variants shallow tillage and direct drilling. Nevertheless, in the subsoil layer the bulk density of soil in the variant with ploughing increased in comparison with other variants. The results were also confirmed by the cone index values. At the plots in Vi&scaron;ňov&eacute; the infiltration was evaluated utilising the double ring infiltrometer, and by means of the coloured water infiltration. The results revealed significant differences in the water infiltration rate at various stages of the soil loosening. The highest average values were recorded for ploughing (1.00 dm<sup>3</sup>/min). The lowest values were found for the shallow soil tillage (0.18 dm<sup>3</sup>/min). The variant with direct drilling showed values of 0.53 dm<sup>3</sup>/min. The coloured water infiltration evaluation showed a different character of water flow in soil. The variant with ploughing showed water saturation in the top layer, the variants with reduced tillage were characterised by vertical macropores and crack effects with the water drain into deeper layers. Ploughing proved its advantage for the short-term rainfall retention. Similar results were also brought in the evaluation on the plot with clay soil (Klap&yacute;). The loosening effect was evident during coloured water infiltration in the period of snow thawing. The loosed soil layer showed a significantly higher soil water holding capacity as compared with variants with reduced soil tillage. The result showed major differences in the water infiltration rate into soil and different characters of water infiltration into soil at different soil tillage.
