Frequently Asked Questions

Irrigation Planning Basics

Q:How do I start planning an irrigation system?

A:Begin by identifying your planting location, crop type, rainfall, evaporation rates, and soil conditions. Understanding your local climate and plant requirements is crucial.

Q:What crop information do I need?

A:Know the crop type, water retention capacity, and planting pattern. These affect water volume, frequency, and distribution method.

Q:How do I estimate water needs?

A:Estimate based on climate (rainfall & evaporation), crop water demand, and soil water-holding capacity.

Water Quality and Soil Testing

Q:Why water quality is important?

A:Water quality affects clogging risk, fertigation compatibility, and crop health. Measure pH, EC, and contaminants.

Q:What soil tests are needed?

A:Measure nitrogen (N), phosphorus (P), potassium (K), pH, and organic matter. Use test kits or digital sensors.

Pump and Filtration Selection

Q:How do I select the right pump?

A:Consider area size, crop demand, lift height, and water source. Match pump power (kW), head (m), and flow rate (m³/h) to requirements.

Q:What filtration system should I use?

A:Choose based on water source (well, river, tank) and quality. Options include screen filters, disc filters, or sand media filters.

Fertigation System Design

Q:What type of fertigation system should I choose?

A:Depends on budget and precision needs. Choose from venturi injectors, pressure-driven units, or fully automated machines with EC/pH sensors.

Q:How many fertilizer channels do I need?

A:Depends on number of fertilizers used. Basic systems use 1-2 channels; advanced systems may use 3+ for N, P, K control.

Energy Source and Automation

Q:What power source options are available?

A:Common options include 220V, 380V electricity, solar panels, or diesel-powered pumps.

Q:Can the system be automated?

A:Yes. Use controllers with timers, WiFi/4G connectivity, and sensors for full automation.

Mainline and Valve Configuration

Q:How do I choose main pipe diameter?

A:Base it on flow rate and field layout. Use pressure gauge and flow meter for sizing.

Q:What additional fittings are needed?

A:Air release valves, check valves, pressure regulators are often required.

Q:Do I need pressure regulators on slopes?

A:Yes. Use pressure regulators on hilly terrain to balance pressure between zones.

Emitters and Field Layout

Q:How do I select emitters?

A:Choose between drip lines, micro-sprayers, and sprinklers based on crop type and water delivery needs.

Q:How do I divide irrigation zones?

A:Group zones by plant type, water needs, and topography. Control each with a separate valve.

Q:How many solenoid valves are needed?

A:One per zone. Choose DC, AC, or pulse valves based on controller type and power supply.

Greenhouse & Sensor Systems

Q:What systems are used in greenhouses?

A:Greenhouses may use grow lights, CO₂ generators, fans, and misting systems, all of which can be automated.

Q:What sensors should I install?

A:Options include soil moisture, NPK, EC, temperature/humidity, CO₂, and light intensity sensors.

Ordering, Samples & Shipping

Q:Where is your company located? How can I visit?

A:Our factory is located in Shijiazhuang, Hebei Province, China. Welcome to visit us.

Q:Can I get a sample, and how long will it take?

A:Yes, we offer samples free of charge — you only bear the freight cost. Samples are sent out within 3 days.

Q:Can I get customized products with my own brand?

A:Sure. Printing your logo on products or packaging is welcome — we have our own design team. See also our OEM services.

Q:What is your MOQ?

A:We accept orders above USD 3,000, and samples can be sent for testing first.

Q:How do you ship the goods?

A:By sea, by air, or by air express — though we don’t recommend sea freight for volumes under 1 CBM.

Q:Can you supply product inspection certificates?

A:Yes, we can supply certification on request.

Q:What is your delivery time?

A:Generally 2–3 weeks after workable payment.

Q:What is your payment term?

A:30% or 50% TT in advance, the balance against the copy of B/L.

Q:How do you handle quality problems after delivery?

A:Send product photos or a video by email, or send a sample by express. Once the problem is confirmed, we will provide a satisfactory solution.
