(21) Simulate the water film formation conditions at the time of tillage parts touching soil, tested the optimal combination of etching Plowshare Steel surface contact angle.

(22) Future research needs to study the dynamics of the compaction problem to determine how frequent moldboard or deep tillage is needed.

(23) I hold that the more arid and unreclaimed the soil where the Christian labourer's task of tillage is appointed him- the scantier the meed his toil brings- the higher the honour.

(24) The activities of sucrase, urease, catalase, cellulolytic enzyme and polyphenol oxidase of the former three treatments were all significantly higher than in the cleaning tillage.

(25) It is more effective to combine water - saving irrigation with agronomy such as tillage and cultivation.

(26) This article obtains from the runoff energy, in the room in the artificial rain experiment foundation, analyzed the slope tillage measure to the runoff energy reduction function.

(27) The main factors of man - made erosion included quarrying, traffic construction , development area building and slope tillage.

(28) Changes of ammonifying, nitrosobacteria, denitrobacteria and anaerobic nitrogen fixing bacteria quantity at different soil dep ths with different tillage patterns .

(29) In this paper the combating drought segment in ridge tillage method and the question in applying were elaborated, and new improving countermeasure and new tillage technology model were raised.

(30) And the fifth way the study found may improve sorghum production is to reduce crop tillage.

(31) Accompanied with herbicide, the quantity of weed seeds in tilth decreased averagely by 75.4% in shallow tillage, and by 27.3% in deep tillage.

(32) A power-driven combined tillage machine belongs to a land preparing implement in the field of agricultural machinery.

(33) As a soil conservation tillage method , ridged - furrow has been applied in sloping field.

(34) Pastures cannot be justified solely because of their contribution to succeeding tillage crops.

(35) Research has shown that deep tillage with a moldboard plough in the monsoon season can overcome this problem.

(36) No - tillage stubble measures can effectively control wind erosion and prevent desertification in Horqin Sandy Land.

(37) Tractor wheel tracks are completely covered after tillage as the working width is much wider.

(38) Effects of different tillage systems on labile organic matter and carbon management index in purple paddy soil of long term experiment site(since 1990) were studied.

(39) This paper analyses the existing problems of paddy field tillage machines in terms of the overall arrangement, stability, tractive ability(), suitability and dynamic characteristics.

(40) Previous experiments show a 14-percent increase in soil organic carbon in the sweep tillage system compared to the moldboard system.

(41) Effects of interplanting with zero tillage and wheat straw manuring(ZIS) on rice growth and grain quality were studied in a wheat-rice cropping system.

(42) This paper analyses soil and water conservation of tillage measures, with reference to rainfall influences.

(43) It features on reasonable structure, firmness for long-lasting operation, easiness to be handled and maintained, even field after tillage without deflective trailed force and so on.

(44) Through fixed field experiment and determinations of soil moisture, the field water utilization efficiency of wheat and rape seeds was discussed under no tillage and straw mulching.

(45) Field experiments were conducted in double cropping rice field during 2005 - 2006 to study the effects of different tillage methods on the changes of rice growth, its yield and soil fertility.

(46) Wheat-Maize double cropping system played a very important role in agriculture production in North China Plain, but the traditional tillage method has hindered sustainable agricultural development.

(47) The methods involve soil fertility management as well as reduced tillage.

(48) The growth and grain yield of summer maize in three kinds tillage management of no tillage, moldboard plowing and sub-soiling under two conditions of stubble mulch and no mulch have been conducted.

(49) Weeds are controlled with precision tillage and the old fashioned hoe.

(50) Another benefit on the farm is that we can now grow our crops with less tillage.
