Maximum Run Time: Allows you to limit the duration of each irrigation. The application takes into account the soil type and depth of the roots so that are no losses. Maximum number of irrigations, seven.

Rain sensor: Selected, watering time is greater, to disregard the rain.
     The rainfall of the previous week and if not watered by rain, should not be taken into account in the balance of this week. It takes into account the maximum usable rain events.

Watering table: Irrigated zones, number of irrigations, run time each irrigation, irrigation flow.

Irrigation recalculated .
Calculating the schedule for the irrigation.

Button All: Start selecting the needs of plants.

Soil type: Choose from three soil types.

Surface:  Zone size.

% Shaded area: Density of plants.

Type of irrigation: sprinkler, drip.

Losses: O unevenness of the installation. It is the water that reaches the ground.

Flow per plant: Number of drippers for its flow rate.

Ratio precipitation: In sprinkling is a feature of the sprinkler.

Emitter flow and emitter/m2: In some plants, can be deduced from the density of planting, plants/m2 and emitters/plant.

Framework: Distance between plants by the distance between streets.

Kv: Vegetation coefficients of plants.

Microclima: Local weather conditions.


What is LandsWater?
It is an application of Urban Landscape irrigation and is an evolution Wucols document.
Landscape coefficient is calculated from a presorting needs of plants, being adapted to the zone by a factor of stress, planting density and microclimate. It takes into account soil evaporation as a lower limit.
A balance is calculated weekly to replenish water in a period of one week, through ETl landscape evapotranspiration, effective rainfall usable and events.
Prepares an annual schedule of irrigation water considering asimilabe easily by plant and soil. Giving rise to a number of watering, the amount and time of irrigation to distribute the current week.

How to get started?
If one is found, the app will search the nearest stations, updating data ETo, rain and events of the past seven days. If a station has no data provide historical average data ETo, having introduced the rest. You can also use another station or manually enter the data.
They use data from 40,000 stations worldwide.
The watering schedule is not updated automatically with the station to have previous data.

What data are needed to irrigate according to ETo?
The application is focused on saving, so that the plants are seeded water as needed. We choose a level of need and the type of plant, obtaining the species that meet.
The landscape will be divided into logically hydrozoning meet a criterion of uniformity needs.
Then you can edit the coefficients of vegetation and stress, we introduce the shaded area as an indicator of coverage, you can edit the dialing microclimate situations that fulfills the area losses finally installing irrigation and losses non-uniformity. In the case of drip irrigation, the number of emitters for surface as well as the flow rate per emitter.
For sprinkler irrigation is needed precipitation ratio, which is measured in mm/h (in/ft) of water falling on the floor of a sprinkler system.
The coefficients of uniformity, runoff losses, etc. should be included as losses.

What type of irrigation is applied LandsWater?
Sprinkler irrigation, micro and drip. In all cases gives the number of irrigation for seven days, the amount of water and time of each watering.

What are the estimated losses?
Is the percentage of water that reaches the plant, due to losses in the system and / or lack of uniformity in irrigation. A good installation will drip losses of less than 15%. Spray losses in lack of uniformity in the distribution may be 30%.

How can LandsWater adapt to drought restrictions?
In lawns using three irrigation levels: Best, deficits and survival according to the drought, the first is without restriction, the second keeps the lawn with lower growth and poorer appearance and the latter serves to recover the lawn to pass the restriction .

Can it work without data LandsWater agroclimatic stations or weather?
Yes, in this case the data of ETo, rain and events must be entered manually. Such data can come from the media database published by government agencies or their own.
A rain event are the days with rain greater than 0.2 x ETo straight days of rain are recorded as a rain event.

How are rainfall data?
Given easily assimilable water, which is a function of soil type, irrigation type and rooting depth, which varies with the plant.

How to use the rain sensor?
The rain sensor is used to stop irrigation in case of rain.
LandsWater has a rain sensor option, if enabled will ignore the rain in the weekly balance, assuming that the rain has saved some watering the previous week.
If the rain did not match any watering and irrigation has saved some, do not select this option, to take account of rain in the balance.
In the Annual Plan for the irrigation, calculated from historical averages do not take into account the rain.

When to use and when to water LandsWater?
LandsWater calculate the real needs.

LandsWater Can be used for urban gardens?
By being able to edit the coefficients of plants with monthly stress coefficients can be used for urban gardens LandsWater, having to enter the same.
There is an application specific IrrglApp crops.

LandsWater can be used for vertical gardens?
There will be a version that includes vertical gardens and irrigation needs for now can act on microclimate coefficients and coefficients of stress.

How to get the highest water saving LandsWater?
In design phase, LandsWater helps you choose plants with few needs, you can choose the most appropriate type of irrigation areas and plan the uniformity criterion.
LandsWater will let you choose an irrigation controller bit tricky because the computational burden will be on your smartphone or tablet.
Measuring soil moisture as an indicator of changes in the reserve, in representative areas and at different depths depending on the roots will help to adapt LandsWater varying operating hours and stress ratios.
Watering is to address the lack of rain and avoid water stress, putting water available to the plants where it is easily assimilated by them, avoiding excessive irrigation and percolation losses and limiting soil evaporation outside the area influence of plants.

What does 1 mm water?
The mm of water column and in turn equal l/m2 or 10 m3/Ha.

How to send data to the irrigation?
We must know the type of controller and remote programming sequence.
LandsWater adapt to send such programming to handle the different valves. Ask us.
