Tillage experiments in the South Australian mallee, over 8 years (1990–97), have demonstrated that cultivation directly below the seed at sowing controls rhizoctonia bare patch as effectively as 1 or 2 cultivations prior to sowing. When combined with a short chemical fallow and the use of press-wheels, this modified direct drilling technique can yield as well as, or better than, conventional farming systems. The combination of modified direct drilling and deep-banded urea increases the control of the disease in the first 2 weeks after the break in the season. In the first 2 weeks after the break, deep banding urea at sowing is more likely to increase yield, than modified direct drilling with urea broadcast at tillering, when both treatments are compared with standard direct drilling. In a reduced tillage system, a cultivation 6–11 days after the break in the season may be more effective in reducing bare patch than a cultivation at other times after the break.

This paper aims to study for accurate sheet trim shower position for paper making process. An accurate position is required in an automation system. A mathematical model of DC motor is used to obtain a transfer function between shaft position and applied voltage. PID controller with Ziegler-Nichols and Hang-tuning rule and Fuzzy logic controller for controlling position accuracy are required. The result reference explains it that the FLC is better than other methods and performance characteristics also improve the control of DC motor.

The performance of a pond–constructed wetland system in the treatment of municipal wastewater in Kiaochow city was studied; and comparison with oxidation ponds system was conducted. In the post-constructed wetland, the removal of COD, TN and TP is 24%, 58.5% and 24.8% respectively. The treated effluent from the constructed wetland can meet the Chinese National Agricultural and Irrigation Standard. The comparison between pond–constructed wetland system and oxidation pond system shows that total nitrogen removal in a constructed wetland is better than that in an oxidation pond and the TP removal is inferior. A possible reason is the low dissolved oxygen concentration in the wetland. Constructed wetlands can restrain the growth of algae effectively, and can produce obvious ecological and economical benefits.

The effects of sowing time (autumn and spring) and technique (conventional cultivation, inverted T direct drill, triple disc direct drill and aerial seeding), on the establishment of tall fescue into a weed infested pasture on the Northern Tablelands of New South Wales were examined. A pre-sowing herbicide treatment was included in the 2 direct drilling treatments, and heavy pre-sowing grazing was used in the autumn sowing. The design used 38 plots of 0.12 ha, analysed as 2 separate, complete block experiments, with some common treatments. Tall fescue establishment, 120 days after the autumn sowing, averaged 48 seedlingslm2 on the inverted T treatment (16% establishment). Establishment was improved by 63%, to 78 seedlings/m2, with herbicide and 46%, to 70 seedlings/m2, by heavy grazing. These effects were additive, giving 105 seedlings/m2 for the combined treatments. Only 52 seedlings/m2 established on the triple disc treatment with heavy grazing and herbicide, while establishment on the cultivated seedbed was not different from the inverted T (93 seedlings/m2). There was no establishment after the aerial seeding at either sowing. Fescue establishment showed the same trends in the spring sowing, with 140 seedlings/m2 on the inverted T treatment with pre-sowing herbicide, which was higher than the establishment of 107 seedlings/m2 on the cultivated seedbed. The fescue yield, 18 months after the autumn sowing, was highest in the autumn sown, inverted T treatment with pre-sowing herbicide and heavy grazing (123 kg/ha). In the spring sowing, fescue was recorded only on the cultivated treatment (84 kg/ha) and on the inverted T treatment with pre-sowing herbicide (39 kg/ha). These results show that tall fescue can be re-established into weed dominated pastures on the Northern Tablelands with direct drilling, in either autumn or spring, and that heavy, pre-sowing grazing and herbicide increase fescue establishment.

Tillage System

Continuous use of traditional tillage system (conventional) resulted in a gradual harvest increase, but gave rise to some worrying negative phenomenon regarding the most important supply of the agricultural production - soil, by its chemical and physical degradation.This paper aims to assess soil degradation processes, based on pedo-transfer rules and is based on of expeditionary studies regarding assessment and characterization of soil fertility, under the practice of various farming systems: conventional tillage and minimum tillage. The study carried out the effects of moderat conservative tillage on physical and chemical soil properties comparative with conventional soil technology on an argic chernozem, belongs to the agricultural Caracal area. Agricultural area is affected by a relatively high variability of the limiting factors and soil degradation processes, which require adaptation of technology systems to protection of soil and plants. Because of all limiting factors, natural and antropic, in this expeditionary study we compare the moderat conservative tillage effects, with conventional technology effects and impact of those both soil technology, on physical, chemical and biological properties. Results of study show the potential depth of aeration conditions are moderately favorable, being determined particularly by intense state of compactness of the soil as a natural consequence of it. Macroporosity decrease in depth, has negative consequences not only on the normal performance of the processes of aeration, and water penetration and infiltration, but for the accumulation of water available for plants. Content of structural microagregates water-stable or soil dispersion is high, which shows that the formation of structural macroagregates occurred more mechanical factors such as compaction or natural processes. The numerical values of the degree of compaction of 15-20 cm in depth up to the 15-18% v / v in both phases of observation. Deep compaction is undoubtedly due to the technological system applied to the greatest extent, and only a small part pedogenetical natural factors.

Microbial preparations improve mineral nutrition of plants, protect against phytopathogens, and increase their resistance to stress factors. The aim of our research is to study the effect of microbial preparations on the biological activity of rhizosphere and the productivity of oil flax under no-till in the Crimean Steppe. Microbiological analysis of the rhizosphere of oil flax showed that there is a tendency to increase the number of microorganisms of various ecological and trophic groups both under the conditions of the conventional farming system (CFS) and no-till when seeds are inoculated with a complex of microbial preparations (CMP). Under CFS, the number of microorganisms using mineral forms of nitrogen as nutrition increased by 28 %; pedotrophs – by 37 %; ammonifiers and oligotrophs increased under both farming systems. The total number of nitrogen fixers increased by 29 % under CFS as a result of biological preparations use, while under no-till there was only a trend towards increasing the amount of azotobacter. The number of actinomycetes increased under the influence of CMP by 50% under direct sowing; micromycetes decreased under both farming systems. The number of cellulose-degrading microorganisms increased by 18 and 27 % under no- till and CFS, respectively. The yield of oilseed flax under no-till was 0.11 t/ha (12.9 %) higher than under conventional farming system. On average, over three years (2017-2019), an increase in yield amounted to 0.12 t/ha (19%) due to the use of microbial preparations.
