Access to watering screen without updating the data.






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 plots or zones, number of irrigations, run time each irrigation,
 water volume at the plot, irrigation flow.

Irrigation recalculated.
Calculating the schedule for the irrigation.





Group: Start selecting the crop.

Soil type: Choose from three soil types.

Surface: Parcel or Zone size.

Diameter Cup: In the case of fruit.

Planting date or start following dormant period in some crops.

Type of irrigation: sprinkler, drip, flood, grooves.

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 crops, can be deduced from the density of planting, 
plants/m2 and emitters/plant.

Framework: Distance between plants by the distance between streets.

Kc: Crops coefficients of crops.

NPK: Formulation of fertilization based on parcel data.


            
         


FAQ

What is IrrglApp?
Is an irrigation app of 200 cultivars, which is based on the FAO method, using the reference evapotranspiration (ETo), rainfall and its events.

How to start?
In the top menu select stations, the application looks ETo , rain and events data of the last seven days of the nearest stations. If a station has no data giving information on the historical average ETo, must introducise the rest. You can also use another station or manually enter the data.
We update daily 11.000 stations that complete the historical average data up to 14,000 stations around the world.

What data are needed to irrigate according to ETo?
It takes a crop, planting date or start and the loss of the irrigation system. In the case of drip irrigation, the planting framework, ie the distance between plants by the distance between streets and the trees where appropriate, and the flow per plant, ie the number of emitters per plant per its flow unit.
In the case of sprinkler is required ratio of precipitation, which is the measure in mm/h of water falling on the floor of a sprinkler system.
The coefficients of uniformity, runoff losses, etc. should be included as losses.

What kind of irrigation is applied IrrglApp?
Sprinkler irrigation, micro and drip, flood, border, furrows and alternate furrows. In all cases gives the number of irrigations for seven days and the amount of water. In the case of drip irrigation and sprinkler gives us the runtime of each watering.

What are the estimated losses?
The percentage of water that reaches the plant, due to losses in the installation and / or lack of uniformity in the irrigation. A good installation will drip losses below 15%. In spray losses due to lack of uniformity in the distribution may be 30%.

How can IrrglApp adapt to drought restrictions?
We have included some crops as deficit irrigation, which are aimed at improving some features production by a slight stress by restricting some of the water, so it can be used in case of drought.

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

Where do IrrglApp agroclimatic data?
Agroclimatic data are calculated daily using the formula of Penmman-Monteith, for the last seven days, using information from temperature, relative humidity, wind speed and radiation stations of national meteorological centers and agroclimatic information networks.

How are rainfall data?
Considering the water easily assimilated, which is a function of soil type, irrigation type and rooting depth, which varies with the crop and its stage of growth.

When should I use irrgApp and when to water?
Should be used every week and if possible on a fixed day, such as Monday. The result of the amount of water, the number of irrigation and where appropriate runtime, can be distributed over the next seven days. This is done weekly balances of inputs and outputs, so should the regularity in the calculation.

Can be used in any country IrrglApp?
Yes, IrrglApp using the location sensor and know what latitude is so use the correct crop coefficients, which vary by season. When choosing an area and month of planting or use startup duration data Kces stages of growth and that have been applied in specific areas. You can use such data for other areas with the limitation that match the durations of the stages. The Kces are recalculated for your climate zone based on historical data of selected agroclimatic station.

Can I use crops from other areas in the mine?
We preferred to keep the original name of the areas where crops have been tested. The right thing would be to speak of climatic zones, for example much of California has a Mediterranean climate, making it possible to use the crop coefficients in both areas. The important thing is to look at the duration of the stages of growth, climate zone is the same and that the month of seed/start match on the same latitude.

How to get the greatest water savings IrrglApp?
The greater saving would be achieved using IrrglApp reference and measuring soil moisture as an indicator of the variation of soil moisture. IrrglApp can be adapted to manage that information and achieve greater savings and higher quality crops.
Watered to address the lack of rain and avoid water stress, making the water available to plants where it is easily assimilated by them, avoiding excessive irrigation and percolation losses and limiting evaporation from the ground outside the area influence the culture.

What is 1 mm of water?
The mm of water column and equal l/m2.
