Plate Method

Bacterial numbers, estimated by the plate method, and carbon dioxide were significantly correlated (r = 0.50–0.69) in field soil during 1955, in an experiment designed to test the effects of straw and crop residues on soil conditions. Differences in moisture, temperature, and soil treatment did not interfere with the correlation.

Spinacia Oleracea L

Spinach (Spinacia oleracea L.) varies in tolerance to saturated soil conditions. Plant vigor was assessed for plants flooded in autoclaved and nonautoclaved field soil. Decline of vigor was more rapid for plants flooded in nonautoclaved field soil, indicating that flooding tolerance may be influenced by soil borne pathogens.

Presented study deals with the resistance of a surface layer created by laser surfacing. Hard surfacing metal powder of type UltrAloy 10611 with a 50 % share of tungsten-carbide particles was used for laser surfacing. Created weld was tested in laboratory conditions (hardness HRC) as well as in field soil conditions (relative wear resistance). Obtained results confirm that this added material is suitable for use in conditions where high abrasive wear is present

Laboratory Bioassays

Weed and cucumber (Cucumis sativusL. ‘Poinsett’) growth was studied where herbicides were soil-applied or applied to emerged weeds in the established crop. Cucumber yields were decreased at least 36% in 2 of 5 yr when weeds interfered for 4 weeks after emergence. Sequential applications of bensulide [O,O-diisopropyl phosphorodithioateS-ester withN-(2-mercaptoethyl)benzenesulfonamide] applied preplant and incorporated (PPI) + trifluralin (α,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine) applied postemergence and incorporated (POI) were outstanding and controlled Japanese millet (Echinochloa crus-galliLink. var.frumentacea), Texas panicum (Panicum texanumBuckl.), Palmer amaranth (Amaranthus palmeriS. Wats.), and common purslane (Portulaca oleraceaL.) without affecting the growth or yield of cucumber. Compared with bensulide, the selectivity of soil-incorporated butralin [4-(1,1-dimethylethyl)-N-(1-methylpropyl)-2,6-dinitrobenzenamine] with cucumber was limited. Laboratory bioassays showed that under warm field soil conditions, PPI applications of 1.7 kg/ha of butralin persisted more than 2 months, but were dissipated after 4 months. Ethalfluralin [N-ethyl-N-(2-methyl-2-propenyl)-2,6-dinitro-4-(trifluoromethyl)benzenamine] reduced cucumber yields only when it was soil-incorporated to the crop-seed depth at planting. Applications to soil of bensulide + DCPA (dimethyl tetrachloroterephthalate) stunted cucumber plants, reduced leaf area, increased leaf thickness, and caused higher near-infrared (0.75 to 1.34 μm) leaf reflectance.

Prescriptive agriculture is the art of science utilizing modern technology to enhance productivity with optimizing inputs/cost. In this paper, the advent of wireless sensor network, APSim, and statistical software spurred a new direction in the farming domain at optimizing irrigation. Sensors are designed to collect the datasets of climatic parameters such as relative humidity and temperature, where the datasets were forwarded to the server through a GSM module. Datasets collected were analyzed through statistical software for grown crops by considering field soil conditions and evapotranspiration. Finally, information on irrigation is determined through an algorithm designed by way2SMS and WebHost server.
