BACKGROUND
Lаwrence Pribil sued Barton and Sandra Koinzan, Terry Held, and Genevieve Shaw (collectively the defendants) for damages that the Koinzans’ cattle inflicted on Pribil’s mature com and soybean crops on several quarter sections of irrigated land. The Koinzans’ cattle escaped from Shaw’s land and went ontо Pribil’s neighboring fields. A summary judgment on the issue of liability was granted, and liability is not disputed in this appeal. In Pribil’s operative petition, he sought $164,079.42 in damages, but the jury returned a verdict for $34,920.60. Pribil appealed, and the Nebraska Court of Appeals affirmed the judgment of the district court. See

v.
Koinzan,
ASSIGNMENT OF ERROR
Pribil’s thrеe assignments of error on further review combine to advance one claim: The Court of Appeals erred in its analysis *224 of the district court’s jury instruction No. 8C, which dealt with damages.
STANDARD OF REVIEW
Whether a jury instruction given by a trial court is correct is a question of law. When reviewing questions of law, an appellate court has an obligation to resolve the questions independently of the conclusion reached by the trial court.

ANALYSIS
The factual details of the case are set forth in the opinion of the Court of Appeals, and most of the facts need not be repeated here, except those that give context tо the issue on further review. Pribil is a 70-year-old farmer with many years’ experience growing com and soybeans on irrigated land southwest of O’Neill, Nebraska. The land is irrigated by center-pivot irrigation systems. These systems work by pivoting a suspended pipe with sprinklers on it around the center of a quarter section, which is usually 160 acres. Thus, each system irrigates only about 130 acres of each quarter section. The irrigated portion of each quarter section is commonly called a circle. In 1996, Pribil raised com and soybeans on 13 circles. The cattle trespassed upon only five circles that were adjacent to Shaw’s lаnd and to each other. It is undisputed that between September 23 or 25 and the end of October, cattle for which the defendants were legally responsible escaped and got into and damaged or destroyed the com and soybeans on these five circles.
Pribil computed his lost yield to be 26,311 bushels of cоm and 2,153 bushels of soybeans on the five circles. Although there was testimony that some of the com had been damaged and replanted in May 1996, prior to the damage inflicted by the Koinzans’ cattle, the evidence indicated that the replanted com had “caught up” with the remaining com by September 25 and was fully mature at that time. Pribil testified that the beans were ready to harvest and that he had stopped watering the com and was waiting for it to dry prior to harvest. In short, the record establishes beyond reasonable dispute that the com and beans were mature crops by the time they were damaged by the Koinzans’ cattle.
*225 The sole issue presented by Pribil’s petition for further review concerns the instructions given to the jury with respect to the measure of damages and Pribil’s burden of proof. Jury instruction No. 8C, given over objection, provided that “[t]he evidence must establish the amount of any item of damage with reasonable certainty or that item of damage cannot be recovered.” Pribil argues that this instruction is in conflict with the standard jury instruction regarding damages, instantiated in this case by instruction No. 6A(3), which provides that “[bjefore [Pribil] can recover against the defendants on [Pribil’s] claim, [Pribil] must prove, by the greater weight of the evidence, the nature аnd extent of the damage to the com and soybean crops.” See NJI2d Civ. 2.12A. Pribil contends, in essence, that “reasonable certainty” is a different burden of proof for plaintiffs’ damages than “the greater weight of the evidence.”
The Court of Appeals rejected Pribil’s argument. The Court of Appeals statеd:
We believe that Worth v. Schillereff,233 Neb. 628 ,447 N.W.2d 480 (1989), is the case which controls the issue presented by instruction No. 8C. Worth was a suit for personal injuries sustained in an automobile accident. The plaintiff sought special and general damages, including future damages .... The court instructed the jury that future damages must be “ ‘reasonably certain.’ ” Id. at 630,447 N.W.2d at 482 . The plaintiff appealеd, arguing that the trial court erred in so instmcting the jury “ ‘when the standard which has been recognized in this state since 1981 is “reasonably probable”.’ ” Id. at 630,447 N.W.2d at 483 . The plaintiff in Worth argued essentially the same point as Pribil argues in this case.
In addition, in holding that an instruction almost identical to the one given by the trial court in this case in instruction No. 8C was not error, the Worth сourt stated: “This court has said that ‘reasonable certainty’ and ‘reasonable probability’ are one and the same thing.”233 Neb. at 633 ,447 N.W.2d at 484 , citing Lane v. State Farm Mut. Automobile Ins. Co.,209 Neb. 396 ,308 N.W.2d 503 (1981). With this statement and holding by the Nebraska Supreme Court, we conclude there is nothing further to discuss. We believe the Worth court *226 clearly held that “reasonable certainty” and “reasonable probability” mean the same thing and that it is not error for a trial court to instruct that damages must be proved by the plaintiff with reasonable certainty, notwithstanding that the plaintiff’s burden of proof is by the greater weight of evidence.
Pribil
v.
Koinzan,
Pribil argues that the Court of Appeals missed the point and that
Worth
v.
Schillereff,
In reviewing a claim of prejudice from instructions given or refused, an appellate court must read the instructions together, and if, taken as a whole, they correctly state the lаw, are not misleading, and adequately cover the issues supported by the pleadings and evidence, there is no prejudicial error. See
Nauenburg v. Lewis,
We have often stated that a plaintiff’s evidence of damages may not be speculative or conjectural and must provide a reasonably certain basis for calculating damages. The general rule is thаt uncertainty as to the fact of whether damages were sustained at all is fatal to recovery, but uncertainty as to the amount is not if the evidence furnishes a reasonably certain factual basis
*227
for computation of the probable loss.
Sack Bros. v. Tri-Valley Co-op,
We hаve consistently framed the question whether the evidence of damages is “reasonably certain” as a question of law, and not as a matter to be decided by the trier of fact. See, e.g.,
Sack Bros.,
supra;
O’Connor
v.
Kaufman,
In other words, the initial question of law for the trial court is whether the evidence of damages provides a basis for determining damages with reasonable certainty, i.e., the evidence of damages is not speculative or conjectural. If the evidence does provide such a basis, the issue of damages can be submitted to the jury. The jury, however, is not charged with the duty of determining whеther the evidence of damages is reasonably certain; rather, the jury is instructed that the plaintiff must prove the nature and extent of damages by the greater weight of the evidence. See, e.g., NJI2d Civ. 2.12A.
The one context in which we have held that the jury is to be instructed that damages must be proved with “reasonable certainty” is when the plaintiff seeks prospective damages, such as recovery for future pain and suffering or loss of earning capacity, and the evidence warrants such an instruction. In those cases, we have held that the jury is to award such damages only where the evidence shows that the future earnings оr pain and suffering for which recovery is sought are “reasonably certain” to occur. See, e.g.,
Snyder v. EMCASCO Ins. Co.,
When the plaintiff seeks рrospective damages, the contingent nature of the damages claimed inherently requires consideration of future events that can only be reasonably predicted, but not conclusively proved, at the time of trial. In such instances, the jury should be instructed, when the evidence warrants, that the plaintiff may rеcover damages for injuries “reasonably certain” to be incurred in the future. See, e.g., NJI2d Civ. 4.01.
Applying these principles to crop damage cases, we note that the measure of damages for the destruction of an
unmatured
growing crop is the value the crop would have had if it had matured, minus any savings to the plaintiff in the costs of producing, harvesting, and transporting the crop to market.
Bristol v. Rasmussen,
On the other hand, we long ago established that the measure of damages for the destruction of a
mature
crop is the difference between the value of the mature crop if there had been no injury and the value of the actual crop harvеsted, less the necessary costs of harvesting and transporting the crop to market. Thus, when a mature crop is destroyed, damages may be proved by showing the market value of the crop, less the necessary costs of finishing, harvesting, and transporting the crop to market. See,
id.; Kula v. Prososki,
In this case, Pribil sought compensation for the damages inflicted on his
mature
com and soybean crops. The damages sought by Pribil were not based on any future contingency; the crops were mature at the time of the destruction, and the damages were fully incurred at the time of trial. Consеquently, the Court of Appeals erred in relying on
Worth
v.
Schillereff,
In an appeal based on a claim of an erroneous jury instruction, the appellant has the burden to show that the questioned instruction was prejudicial or otherwise adversely affected a substantial right of the appellant.
Nauenburg
v.
Lewis,
We note, for the sake of completeness, that three opinions of this court discuss jury instructions in which the jury was informed that the plaintiffs, seeking past and present damages, were nonetheless required to establish damages with “reasonable certainty.” See,
Colvin v. Powell & Co., Inc.,
CONCLUSION
The Court of Appeals erred in affirming the judgment of the district court with respect to the issue of damages, because the district court’s instruction that Pribil’s evidence must establish the amount of damages with “reasonable certainty” was not warranted by the evidence in this case and was prejudicial to Pribil. Pribil did not seek further review of the other determinations of the Court of Appeals, so those issues are not before us and, on remand, stand as decided. See
