Answer

What are the advantages of laser leveling in agriculture?

Laser leveling results in a precisely leveled field −− resulting in more evenly maturing crops, higher yields and reducing water and agro-chemical use. Plow the field when the soil is moist. Dry soil requires a significant increase in tractor power.

What is laser land levelling?

Laser land levelling ensures sustainable agriculture in combination with other energy saving technologies like solar based irrigation. A laser land leveller machine is effective and simplifies the work giving the best results. The tabletop is flattened evenly hence ensuring efficient water supply to every part of the land during irrigation.

What is laser level in surveying?

In surveying and construction, the laser level is a control tool consisting of a rotating laser beam projector that can be affixed to a tripod. The tool is leveled according to the accuracy of the device and projects a fixed red or green beam in a plane about the horizontal and/or vertical axis.

What is a rotary laser level?

Rotary laser level. A rotary laser level is a more advanced laser level in that it spins the beam of light fast enough to give the effect of a complete 360 degree horizontal or vertical plane, thus illuminating not just a fixed line, but a horizontal plane.

Plow the field from the center of the field outwards

Plow the field when the soil is moist. Dry soil requires a significant increase in tractor power.


Take a topographic survey of high and low areas

Take a topographic survey of the field, then draw a diagram noting high and low areas.


Check and calibrate the laser transmitter

Periodically check the laser transmitter for accuracy. All checking and calibration procedures are done at the zero slope reading.


To check accuracy

A suitable tripod that allows you to rotate the transmitter in 90 degree increments


Level the field

The laser-controlled bucket should be positioned at a point that represents the mean height of the field.


Re-survey the field

Re-survey the field to make sure the desired level of precision has been attained.


Where is laser leveling used?

Laser leveling systems are commonly used in agricultural applications in Australia, Japan and the United States. Increasingly, laser guided systems are being used in lesser developed country contexts as well.


How does a laser leveler work?

A laser transmitter transmits a laser beam, which is intercepted by the laser receiver mounted on the leveling bucket. The control panel mounted on the tractor interprets the signal from the receiver and raises or lowers the bucket. This way the soil gets shifted to the right places to make the entire field level.


Why is land leveling important?

2. Better weed control. Land leveling increases yield to a large extend because it improves weed control. Improved water coverage from better land leveling reduces weeds by up to 40%. This reduction in weeds results in less time for crop weeding. 3. Larger farming area. Good land leveling enables larger fields.


What are the benefits of leveling rice?

1. Higher yield . Good field leveling increases the rice yield considerably. In two experiments conducted at different localities, a strong correlation was found between the levelness of the land and crop yield. 2.


When was the laser level invented?

The concept of a laser level has been around since at least the early 1970s, the original spinning-mirror design laser plane and line level was patented by the late 1980s, and the compact lens-based laser line level (as produced by many tool manufacturers today) was patented in the late 1990s.


What is rotary laser level?

A rotary laser level is a more advanced laser level in that it spins the beam of light fast enough to give the effect of a complete 360 degree horizontal or vertical plane, thus illuminating not just a fixed line, but a horizontal plane.


What is a tower mounted laser level?

A tower-mounted laser level is used in combination with a sensor on a wheel tractor-scraper in the process of land laser leveling to bring land ( for example, an agricultural field) to near-flatness with a slight grade for drainage .


What is laser beam projector?

The laser beam projector employs a rotating head with a mirror for sweeping the laser beam about a vertical axis. If the mirror is not self-leveling, it is provided with visually readable level vials and manually adjustable screws for orienting the projector.


1. Reduction in time and water for irrigation

These are the two most important features of this modern technology. Save time and water. Did you know that laser leveling reduces your time by up to 50 hours per hectare? Imagine how important this is for you, and then look at the ecological significance. It is certainly not your goal to make the most of natural resources without taking your time.


2. Even water distribution

Saving water is not only good for preserving the natural environment but also for you and your business. The bigger your business is, the more responsibility you have in performing key tasks. Irrigation is a crucial factor for every farmer and things can easily go in the wrong direction.


3. Energy saving

Savings when using laser leveling are not only present in the irrigation section, but also in terms of energy. So far, there has been a big difference in energy consumption. The reduction in electricity use is up to 700 kWh per hectare per year.


4. Cost

There are misconceptions that this technology can only be afforded by farmers who have huge land, but of course that is not true. The price of this processing is not particularly high and it can be said that it is neutral – availability is possible for smaller farmers as well as larger ones.


USE LESS WATER, GET BETTER RESULTS

A properly leveled (or slightly sloped) field promotes even and efficient irrigation. You use less water, the crop grows better and more evenly, and your soil is retained.


DURABILITY, VISIBILITY, REPEATABILITY

Topcon laser land leveling solutions have been at work for decades, and that experience results in a rugged dependable solution delivering great accuracy repeatably, year in, year out. Each component of the solution is optimized with the features that matter and are easy to use.


6.1 The importance of land preparations

Levelling, smoothing and shaping the field surface is as important to the surface system as the design of laterals, manifolds, risers and outlets is for sprinkler or trickle irrigation systems.


6.2 Small-scale land levelling

Most small-scale farming operations rely on animal power or small mechanized equipment which an individual can own and operate. As the irrigator waters his fields season after season he is able to observe the locations of high and low spots on the field.


6.4 Laser land levelling

The advent of the laser-controlled land levelling equipment has marked one of the most significant advances in surface irrigation technology. One such system is shown in Figure 69. It has four essential elements: (1) the laser emitter; (2) the laser sensor; (3) the electronic and hydraulic control system; and (4) the tractor and grading implement.
