Farm Irrigation Solutions in Texas: Choosing the Right System for Your Operation

Texas agriculture faces a fundamental challenge: producing crops in a state where rainfall varies from 8 inches annually in the west to 56 inches in the east—and where you can never count on rain arriving when crops need it most.

The solution for most commercial farming operations is irrigation. But with multiple system types, technologies, and price points, choosing the right irrigation solution requires understanding your specific situation.

This guide compares the major irrigation options available to Texas farmers and helps you evaluate which fits your operation.

Texas Irrigation Overview

Current State of Texas Irrigation

Texas has approximately 5.6 million irrigated acres, making it one of the largest irrigated states in the country. The breakdown:

Groundwater:

• • Ogallala Aquifer (Panhandle and South Plains)
• • Gulf Coast Aquifer
• • Edwards Aquifer (Central Texas)
• • Various smaller aquifers

Surface Water:

• • Rio Grande (far south)
• • Colorado River system
• • Brazos River basin
• • Various irrigation districts

Water Challenges

Declining Aquifers: The Ogallala, which supplies most High Plains irrigation, is declining faster than it recharges. Efficiency is increasingly critical.

Regulatory Pressure: Groundwater conservation districts are implementing stricter allocation limits in many areas.

Rising Costs: Energy costs for pumping, especially from deep wells, continue to increase.

Climate Variability: Droughts are intensifying. The 2011 drought cost Texas agriculture over $7 billion.

Irrigation System Options

Center Pivot Systems

Center pivots dominate Texas irrigated agriculture for good reason—they're efficient, relatively low-labor, and adaptable to a wide range of crops and conditions.

How They Work: A wheeled tower system rotates around a fixed center point, covering a circular area. The outer end moves faster than the inner sections, so nozzle sizes increase toward the end to maintain uniform application.

Best For:

• • Large, relatively flat fields (80+ acres)
• • Row crops (corn, cotton, soybeans, wheat)
• • Operations with limited labor
• • Areas with adequate water supply (400+ GPM)

Pros:

• • High efficiency (85-95% water reaching crops)
• • Low labor requirement
• • Uniform application
• • Automation capability
• • Long service life (25-30 years)
• • Adaptable to various crops

Cons:

• • Significant capital cost ($50,000-250,000)
• • Leaves corners unirrigated (unless corner system added)
• • Requires reliable power source
• • Not ideal for irregularly shaped fields

Texas Considerations: Center pivots perform well across most of Texas. In the High Plains, they've largely replaced flood irrigation for water efficiency. In blackland areas, careful nozzle selection prevents runoff on heavy soils.

Linear/Lateral Move Systems

Linear systems cover rectangular fields by moving in a straight line rather than rotating.

How They Work: Similar construction to center pivots, but the entire system travels the length of the field. Water supply comes from a moving hose, canal, or buried pipe with risers.

Best For:

• • Long, narrow fields
• • Rectangular field shapes
• • Fields where center pivot corners would be problematic
• • Properties with canal or ditch water supply

Pros:

• • Covers entire rectangular area
• • No corner losses
• • Same efficiency as center pivots
• • Works with canal systems

Cons:

• • More complex water supply
• • Higher maintenance than pivots
• • Fewer acres per dollar of investment
• • Guidance system required

Texas Considerations: Linear systems work well in South Texas where canal irrigation is common and field shapes favor rectangular coverage.

Drip Irrigation

Drip systems deliver water directly to plant root zones through emitters in tubing laid along crop rows.

How They Work: Low-pressure water flows through plastic tubing with small emitters that release water slowly. Can be surface-laid or buried.

Best For:

• • High-value crops (vegetables, orchards, vineyards)
• • Limited water situations
• • Saline or poor-quality water
• • Sloped ground
• • Small or irregularly shaped fields

Pros:

• • Highest efficiency (90-97%)
• • Precise water and nutrient delivery
• • Works with low water volume
• • Reduced weed pressure between rows
• • Lower energy costs (low pressure)

Cons:

• • Higher cost per acre than pivots
• • Labor-intensive maintenance
• • Clogging potential requires filtration
• • Rodent and insect damage risk
• • Annual setup for annual crops

Texas Considerations: Expanding rapidly in South Texas vegetable production, orchards, and vineyards. Increasingly used for cotton in water-limited areas. Subsurface drip (SDI) gaining popularity for permanent installations.

Flood/Surface Irrigation

Traditional method where water flows across fields by gravity.

How They Work: Water is released at the high end of a field and allowed to flow downslope, soaking into the soil. Includes furrow, border, and basin methods.

Best For:

• • Very flat land with proper grade
• • Situations with high water availability
• • Low-cost water sources
• • Rice production
• • Some specialty crops

Pros:

• • Low capital cost
• • Simple technology
• • Works with any water source
• • Effective for rice

Cons:

• • Lowest efficiency (50-70%)
• • High water requirement
• • Labor intensive
• • Land leveling required
• • Not suitable for sloped ground

Texas Considerations: Still used for rice in the Gulf Coast region and some situations where water is abundant and cheap. Being replaced by more efficient methods in most other areas.

Sprinkler Systems (Non-Pivot)

Includes traveling guns, solid-set systems, and hand-move pipe.

How They Work: Sprinklers distribute water over the crop in various configurations, either permanently installed or moved periodically.

Best For:

• • Smaller fields
• • Irregularly shaped areas
• • Supplemental irrigation
• • Pasture irrigation
• • Situations requiring flexibility

Pros:

• • Lower initial cost than pivots
• • Flexible coverage
• • Can irrigate any field shape
• • Various technology levels available

Cons:

• • Higher labor for most types
• • Lower efficiency than pivots
• • Wind drift issues in Texas
• • More maintenance

Texas Considerations: Hand-move and wheel-line systems work for smaller operations. Traveling guns are used for some pasture and hay operations. Generally being replaced by pivots where field size allows.

Choosing the Right System

Key Decision Factors

Field Size and Shape: | Field Type | Best Option | |------------|-------------| | 80+ acre squares | Center pivot | | Long rectangles | Linear system | | Small/irregular | Drip or sprinkler | | Flood-suited flat land | Surface irrigation |

Water Availability: | Water Situation | Best Option | |-----------------|-------------| | 400+ GPM, reliable | Center pivot | | 200-400 GPM | Pivot or drip | | Under 200 GPM | Drip irrigation | | Unlimited (rare) | Any system |

Crop Type: | Crop | Typical System | |------|----------------| | Cotton, corn, wheat | Center pivot | | Vegetables | Drip or pivot | | Orchards/vineyards | Drip | | Rice | Flood | | Hay/pasture | Pivot or sprinkler |

Budget: | Investment Level | Options | |------------------|---------| | Under $25,000 | Drip (smaller area), sprinkler | | $25,000-75,000 | Small pivot, drip system | | $75,000-150,000 | Standard pivot, large drip | | $150,000+ | Large pivot, multiple systems |

Decision Framework

Ask these questions in order:

1. What's my water source and capacity? Low water availability may rule out flood and limit pivot options.

2. What's my field size and shape? Small or irregular fields limit economical pivot use.

3. What crops am I growing? High-value crops can justify higher-cost drip systems.

4. What's my labor availability? Limited labor favors automated pivots over labor-intensive options.

5. What's my budget—capital and operating? Consider total cost of ownership, not just purchase price.

6. What's my management capacity? Advanced technology requires management commitment.
